H09R9x is a thermopile sensor module based on STM32G0 MCU and TSD305 digital temperature sensor.  

  • The TSD Series are digital thermopile sensors in a TO5 package.
  • The TSD sensors include an infrared sensor (thermopile) and a sensor signal conditioner.
  • The TSD sensors can be interfaced to any microcontroller by an I2C interface. This microcontroller has to calculate the temperature results based on the ADC values and the calibration parameters

Use this module for contactless temperature measurement, climate control, industrial process control or household applications. Connect with other Hexabitz modules to log sensor measurements, stream data wirelessly or control external devices based on sensor readings.
