Frequently Asked Questions

An air quality sensor measures pollutants such as particulate matter (PM1.0, PM2.5, PM10), gases (CO, SO2, NO2, O3) and VOCs, often alongside environmental data like temperature, humidity and pressure, depending on the model.

PM2.5 sensors in the ZAQ range use laser scattering. Airborne particles pass through a laser beam and the light they scatter is measured to calculate particle concentration, with a range of 0-1000 μg/m³ and resolution of 0.3 μg/m³.

A VOC sensor detects volatile organic compounds using a photoionization detector (PID), reporting a value in ppm or ppb. A particle sensor measures solid airborne particles such as dust using laser scattering, reporting a value in μg/m³. They measure different pollutant types and are not interchangeable.

Yes. The outdoor air quality monitoring station range (ZAQ220 to ZAQ670) is housed in outdoor industrial-grade ASA plastic and rated IP55 overall, with IP67 on temperature/humidity sensing and IP68 on pressure and noise sensing.

ZAQ sensors support RS485 and RS232 as standard wired interfaces, with WiFi, Bluetooth and LTE available, and optional Zigbee, NB-IoT, LoRa or GPRS modules on certain models.

PM1.0, PM2.5 and PM10 readings from the ZAQ range have a stated accuracy of ±15% or ±10 μg/m³, whichever is greater, with a resolution of 0.3 μg/m³.

Model selection depends on which parameters are needed. The ZAQ220 and ZAQ620 cover core gases and particulates only, the ZAQ350 and ZAQ360 add wind, pressure and noise, and the ZAQ370, ZAQ380 and ZAQ670 add solar radiation, UV index and illumination on top of that.

A single-parameter sensor, such as the ZWQ-PH1 pH electrode, measures one property only. A multi-parameter meter, such as the ZWQ500, combines several sensing elements (temperature, pH, conductivity, dissolved oxygen, turbidity, with COD, chlorophyll or cyanobacteria as options) in one probe body connected through a single cable.

All sensors in the Zata IoT water quality range communicate over RS485 using the Modbus RTU protocol. The ZWQ500 multi-parameter meter additionally supports RS232, WiFi, Bluetooth and optional LTE.

This depends on the sensor. The dissolved oxygen sensor (ZWQ-DO1) uses fluorescence measurement and does not need initial calibration or electrolyte replacement. Electrode-based sensors such as pH, ORP, ammonia, fluoride and chloride use ion-selective or glass electrodes, which typically need periodic calibration as part of routine maintenance.

The turbidity (ZWQ-TUB1), COD (ZWQ-COD1), transparency (ZWQ-TP1), chlorophyll (ZWQ-CHL1) and blue-green algae (ZWQ-BGA1) sensors all include a self-cleaning function, either a brush or automatic wiper, because their optical windows are prone to biofouling in continuous deployment.

Most sensors in the range run on DC 12V or 24V. The ZWQ500 multi-parameter meter also supports solar power. The residual chlorine sensor (ZWQ-CT1) and turbidity sensor (ZWQ-TUB1) have slightly different supply specifications, so check the individual product page before ordering.

The residual chlorine sensor (ZWQ-CT1) is specifically listed for tap water, secondary water supply and swimming pool applications. It requires a continuous sample flow of 250-500 mL/min and operates within a pH range of 4-9.

A compact weather sensor such as the Zata ZWS series combines multiple measurement channels, for example wind speed, wind direction, temperature, humidity, pressure and rainfall, in a single housing with one mounting point and one communication interface. Separate individual sensors, such as a standalone anemometer or a standalone rain gauge, measure one parameter each and are mounted and wired independently. Compact sensors simplify installation; separate sensors allow replacing or upgrading one parameter without affecting the others.

RS485 with Modbus protocol is the standard interface across the Zata IoT range. Many models also offer RS232, SDI-12, WiFi, Bluetooth, LTE, LoRa or NB-IoT as optional interfaces, so the sensor can connect to a range of data loggers, PLCs or IoT gateways.

Yes. Most sensors in this range accept DC 12/24V input and are compatible with solar power supply, with typical current draw under 15-20 mA at 12V, which suits remote or off-grid monitoring sites.

Most sensors in the range operate from -40°C to +85°C. Some models, including the ZWS compact weather station family, are rated down to -60°C, and specific instruments such as the ZAB UV radiometer are rated to -50°C to +100°C. Exact figures vary by model and are listed on each product page.

Outdoor sensor bodies are typically rated IP66 or IP67, with pressure-sensing components rated IP68 where listed. This allows the sensors to be mounted outdoors and exposed to rain and dust without additional enclosures.

No. MetSensor UK is a UK reseller and distributor of Zata IoT sensors. The sensors are manufactured by Zata IoT; MetSensor UK supplies them to UK buyers with UK-based support and quote-based pricing.

Start by listing the parameters you need to measure, for example wind speed, rainfall, or solar radiation, then compare the measurement range, accuracy and communication interface listed on each product page against your project requirements. Contact MetSensor UK with your project details if you need help matching a model to your application.

Yes. The range includes sensors designed specifically for agriculture, such as the ZSPH soil pH sensor, ZLW-2 leaf wetness sensor and ZSTM-3 soil moisture, EC and temperature sensor, alongside compact weather sensors used for general field weather monitoring.

An automatic weather station measures atmospheric parameters such as temperature, humidity, pressure, wind speed, wind direction and rainfall, and some models add solar radiation, visibility or road surface conditions. The Zata IoT range supplied by MetSensor UK covers all of these parameters across different station types.

A weather sensor is a single- or multi-parameter module, such as a rain gauge or anemometer, that measures one aspect of the weather. A weather station is a complete system that combines several sensors, a housing and a communication interface, built for a specific site such as a road, solar farm or power line.

Zata IoT weather stations and sensors typically support RS485 and RS232 for wired connections, plus WiFi, Bluetooth and optional LTE/4G for wireless data transmission. Compact sensor modules communicate using the Modbus protocol.

Most Zata IoT weather stations use an IP65 or IP55 rated enclosure, with IP67 protection on the temperature and humidity sensors and IP68 on the pressure sensor, which protects the equipment against dust ingress and heavy rain in outdoor installations.

Yes. Most Zata IoT weather stations and sensors have an operating temperature range down to -40°C or -50°C, and the ZTLS transmission line station offers an optional heating function for extreme cold, which covers UK winter conditions.

If you need to monitor several parameters at a fixed site, a complete station such as the ZTS, ZPVS or ZMT is usually the right choice. If you only need one parameter, such as rainfall or wind speed, a standalone sensor from the ZWS-series or a dedicated rain gauge or anemometer is more cost-effective.

Zata IoT weather stations store recorded data on board for more than 5 years, in addition to transmitting live readings over RS485, RS232, WiFi, Bluetooth or LTE/4G.

No. MetSensor UK is the official UK reseller of Zata IoT weather stations and sensors. We do not manufacture the equipment; we supply it to UK customers on a quote basis with UK-based support.

Ultrasonic anemometers have no mechanical parts to recalibrate for wear, though the speed-of-sound reading is temperature-dependent and factory-compensated.

Yes. Without moving cups to seize, ultrasonic anemometers such as the ZWS200 continue producing accurate wind data through light icing.

For submersion resistance, yes. But a sensor that will never be submerged doesn't need IP68, and it doesn't improve dust protection over IP67.

Different components inside the same housing can be sealed differently, so a compact weather sensor can carry separate ratings for its temperature/humidity module and its pressure-sensing element.

Yes. Each sensor gets a unique Modbus address, and many sensors can share the same two-wire bus and data logger.

RS485 can reliably run up to roughly 1200 metres, far beyond RS232 or most wireless options.

Weighing rain gauges tend to hold up best in heavy rainfall since they measure accumulated mass directly rather than counting discrete bucket tips.

A pyranometer measures total solar radiation (direct plus diffuse). A pyrheliometer isolates only the direct beam and needs a sun-tracking mount.

Yes, both use RS485/Modbus and can share one bus with unique Modbus addresses per sensor.

No, the ZRS uses non-contact near-infrared laser measurement from above the road surface.

A pyranometer for solar radiation and a panel-dust detection feature, aimed at PV-specific performance analysis.

The ZAQ650 series covers the core regulated gas pollutants (CO, SO2, NO2, O3) alongside particulates.

Yes, every sensor family shares RS485/Modbus RTU as a baseline interface, so a city-scale network can mix sensor types on shared infrastructure.

The ZD-EAR uses a microphone array of up to 208 channels to triangulate acoustic signatures characteristic of drone rotors, confirmed visually with its camera.

The ZWQ500 suits long-term or rapid on-site deployment; separate probes suit projects needing more parameters or higher per-parameter accuracy.
