1.. when the environment temperature reach setting threshold, output high level DO end, when
The environment temperature more than set threshold, output DO low level.detection
Temperature can be adjusted through the potentiometer, clockwise adjust potentiometer, temperature detection
Increased;Counter-clockwise adjust potentiometer, detect temperature decrease.
2. The comparator output, signal clean, good waveform, driving ability.
3. The sensor module output port OUT can be directly connected to the microcontroller IO port namely
But, also can drive a 5 v relay directly;Connection mode: the VCC –
VCC.GND – GND;The OUT – IO
4, can use 3.3 V to 5 V dc power to power supply module.When the power supply switch on
When the red power indicator light;
5, the module of temperature detection range of 20-80 degrees Celsius;
6, this module can also be replaced with a line of temperature sensor, used for water temperature,
The control of water tank, etc.
