  • Adopt the NTC thermistor sensor, sensitivity is good
  • The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma.
  • With potentiometer to adjust temperature detection threshold
  • Working voltage: 3.3 V to 5 V
  • Output form: digital switch output (0 and 1)
  • It has a fixed bolt hole, convenient installation
  • Small board PCB size: 3.2 cm x 1.4 cm
  • Using the LM393 wide voltage comparator


  • A thermistor module is sensitive to the environment temperature, are commonly used to detect the temperature of the surrounding environment;
  • Through to the potentiometer adjustment, can change the temperature detection threshold (i.e., temperature control), such as the need to control the environment temperature is 50 degrees, while the module corresponding environmental temperature to the green light, the DO output high level, below the set temperature, the output high level, green light don’t;
  • The DO output can be attached directly to the single chip microcomputer, through single chip microcomputer to detect the high and low level, thus to detect the temperature of the environment change;
  • The DO output can be directly driven our relay module, which can form a temperature control switch and control related equipment operating temperature, also can connect the fan used for cooling, etc.;
  • The module of temperature detection range of 20-80 degrees Celsius;
  • This module can also be replaced with a line of temperature sensor, used for water temperature, the control of water tank, etc.
