Humidity & Temperature Sensor HSM-20G

  • RM30.00

  • Product Code: Humidity Sensor Module HSM-20G
  • Availability: In Stock

Available Options

The HSM-20G is an analog humidity and temperature sensor that outputs analog voltage respects to relative humidity and temperature. However from this sensor relative humidity is found along with temperature. Relative humidity is the percentage of moistures of air for a particular temperature. 



HSM-20g is considered as the most operating sensor compared to other similar products. This sensor is used in BTS (base transmission station) for weather forecasting. Also it is used in:

  • Humidifiers & dehumidifiers
  • Air-conditioner
  • Humidity data loggers
  • Automotive climate control
  • Weather monitoring system  



  • Sensor is composed of a resistive humidity sensing component and an NTC temperature testing component and connects with 8-byte MCU
  • MCU outputs a digital code
  • Fast response and great anti-interference capability
  • Durable and long lasting sensor
  • Low power consumption
  • Based on the DHT11 sensor architecture
