Product Description
The RS485 Temperature Humidity Transmitter Sensor (also called temperature and humidity module) HRTM030 is a kind of temperature and humidity sensor. It is widely used in the electronic, textile, storage, tobacco, pharmaceutical and other industries. The sensor has good consistency and strong stability.
1. Induction humidity components: polymer humidity sensitive resistor
2. Induction temperature element: NTC thermistor
3. The working temperature: -20ºC~60ºC Working humidity: 20% ~ 95% RH;
4. Accuracy of measurement: humidity: ±3% RH temperature:±1ºC
5. Humidity output signal:(25ºC,The output voltage=5V)
