What weather sensors measure
Weather sensors convert physical atmospheric or ground conditions into electronic signals that a data logger, controller or IoT platform can record. Depending on the sensor type, this includes wind speed and direction, air temperature, relative humidity, barometric pressure, rainfall intensity, solar radiation, UV index, visibility, cloud height, soil moisture and pavement condition. A single compact weather sensor such as the ZWS series can combine several of these parameters into one housing, while dedicated instruments such as pyranometers or disdrometers measure one parameter to a higher level of detail.
How the sensing technologies work
Each parameter uses a specific sensing principle. Wind speed and direction on the Zata ZWS and ZUA3 range use ultrasonic time-of-flight measurement between transducers, which has no moving parts and continues to operate in icing conditions where cup anemometers can seize. Rainfall is typically measured piezoelectrically (ZWS100, ZWS series) or with a tipping bucket mechanism (SL3-1, ZDR100), where each bucket tip generates a reed switch pulse proportional to a fixed volume of rain. Temperature and humidity use digital MEMS sensing elements, and pressure uses a silicon piezoresistive element. Solar radiation sensors use thermopile or silicon photodetector technology, and visibility sensors use forward-scattering or backscattering of an infrared beam to infer atmospheric extinction. Road and pavement sensors use non-contact infrared laser measurement to detect water, ice and snow film thickness.
Key specifications to compare
Buyers should compare five specification areas before selecting a sensor: measurement range (for example 0-60 m/s wind speed or 300-1150 hPa pressure), accuracy and resolution (for example ±0.3°C temperature accuracy at 0.1°C resolution), operating temperature range (Zata sensors typically operate from -40°C to +85°C, with some models extending to -60°C), communication interface (RS485 Modbus is the standard interface across the range, with RS232, WiFi, Bluetooth, LTE, SDI-12, LoRa and NB-IoT available as options on many models), and IP protection rating (IP66/IP67 for outdoor housings, IP68 for submerged or pressure-sensing components). Power supply also matters for remote sites: most Zata sensors run on DC 12/24V and accept solar power input, drawing under 15-20 mA at 12V in normal operation.
Typical applications and industries
Weather sensors from this range are used in hydrometeorological and meteorological standard stations, regional and research automatic weather stations, urban waterlogging and flood monitoring, smart city and smart street lighting projects, agricultural and forestry monitoring, wind power site assessment and turbine monitoring, transmission line and tower crane monitoring, airport meteorological observation (AWOS), highway and road weather information systems (RWIS), and marine and offshore installations. The specific application determines which sensor category and which combination of measured parameters is appropriate.
How to choose between models in this category
Start from the parameters you need to measure, not the model number. If you only need temperature, humidity, pressure and rainfall, a smaller compact sensor such as the ZWS400 covers that without paying for wind and radiation channels you will not use. If you need wind speed and direction plus the core four parameters, step up to the ZWS500 or ZWS600. If you also need solar radiation and UV index, the ZWS700 or ZWS800 add those channels. For dedicated wind measurement over a longer boom or at higher accuracy, the ZWS200 ultrasonic anemometer or the 3-axis ZUA3 are built specifically for that task. For precipitation type and intensity beyond a basic rain gauge, the ZDM100 disdrometer reports particle size distribution and precipitation type as well as rate. Match the communication interface to your existing data logger or telemetry system: RS485 Modbus is the common baseline, and cellular (LTE) or LoRa variants suit remote sites without wired infrastructure.

Frequently asked questions
What is the difference between a compact weather sensor and separate individual sensors?+
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.
What communication interface do these weather sensors use?+
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.
Can these sensors run on solar power?+
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.
What operating temperature range do the sensors cover?+
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.
What IP rating do the outdoor sensor housings have?+
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.
Does MetSensor UK manufacture these sensors?+
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.
How do I know which sensor model to choose for my project?+
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.
Are these sensors suitable for agricultural monitoring?+
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.
