product detail
Product characteristics:
The thermistor module is very sensitive to the ambient temperature. It is generally used to detect the temperature of the surrounding environment. NTC thermistor sensor is used with good sensitivity. The temperature detection range is 20-80 ℃. The sensor is equipped with an M3 fixed mounting hole, which is easy to use for adjusting the direction and fixing. The wide voltage LM393 comparator is used. The signal is clean, the waveform is good, and the driving capacity is strong, exceeding 15mA. It is equipped with an adjustable precision potentiometer to adjust the sensitivity.
Product parameters:
Working voltage: DC3.3-5V
By adjusting the potentiometer, you can change the temperature detection threshold (that is, the control temperature value). If you need to control the ambient temperature to 50 degrees, the module will output a low level when the corresponding ambient temperature is adjusted to its green light, and the DO will output a high level when it is lower than the set temperature value, but the green light will not be on; The digital output D0 of the module can be directly connected with the microcontroller to detect the high and low levels through the microcontroller, thereby detecting the temperature change of the environment; The small board digital output DO can directly drive the relay module, which can form a temperature control switch to control the working temperature of related equipment, and can also be connected to a fan for heat dissipation; Small board analog output AO can be connected with AD module, and more accurate values of ambient temperature can be obtained through AD conversion. This module can also be replaced with a wired temperature sensor for the control of water temperature, water tank, etc.
After connecting VCC and GND, the module power indicator will light up. Place the module on the desktop, adjust the blue potentiometer on the board until the switch indicator on the board lights up, and then slightly back up to make the switch indicator off, and then try to raise the temperature of the thermistor. At this time, the module switch indicator will light up. If the temperature of the thermistor is lowered again, the switch indicator will return to the off state. This phenomenon shows that the ambient temperature can trigger the module, thus making the switch indicator light on.
