ZWS640 All-in-One Compact Weather Sensor
ZWS640
The ZWS640 is an all-in-one compact weather sensor that measures wind speed, wind direction, temperature, humidity, pressure, rainfall, compass heading and acceleration in a single Ø110 mm x 245 mm housing. It is supplied in the UK through MetSensor UK, a Zata IoT reseller.
- ✓ Nine measured parameters in one housing: wind, temperature, humidity, pressure, rainfall, compass, earthquake grade, acceleration
- ✓ Ultrasonic wind speed and direction sensing, no moving parts
- ✓ Digital MEMS temperature and humidity sensing
- ✓ Piezoelectric rainfall detection
- ✓ IP67 (temp/humidity) and IP68 (pressure) rated
- ✓ DC12/24V or solar power operation
