20pcs Thermal Sensor Module Temperature Switch Thermistor Sensor Board

Uses Temperature detection temperature control sensors ambient temperature detection Features 1 Using the NTC thermistor sensor good sensitivity2 The comparator output signal is clean good waveform driving ability more than 15mA 3 Adjust the temperature distribution position detection threshold4 The working voltage 3 3V 5V5 The output format digital switching outputs 0 and 1 6 Fixed bolt holes for easy installation7 Small PCB board size 3 2cm x 1 4cm8 Using a wide voltage LM393 comparator Module for use 1 The thermal resistance of the module is very sensitive to the ambient temperature typically for detecting the temperature of the surrounding environment 2 Through the potentiometer adjustment you can change the temperature detection threshold ie control temperature such as the need to control the ambient temperature is 50 degrees the module in the corresponding ambient temperature to its green light DO high power output when flat set the temperature below this value the output is high the green light does not shine 3 DO output can be directly connected to the microcontroller through the microcontroller to detect high and low thereby detecting temperature changes in the environment 4 DO output of the relay module can directly drive the shop which can be composed of a thermostat to control the temperature of work related equipment can also be connected to the cooling fan etc 5 The temperature detection range of the modules 20
