Description: Descriptions: Product Features:Thermistor module is sensitive to ambient temperature, generally used to detect the temperature of the surrounding environment, using NTC thermistor sensor, good sensitivity. The temperature detection range is 20-80 degrees Celsius. Sensor ad hoc M3 fixed mounting holes, adjusting the direction and fixed convenient and easy to use, using a wide voltage LM393 comparator, clean signal, good waveforms, driving capacity, more than 15mA, with adjustable precision potentiometer to adjust the sensitivity. Product parameters:Operating voltage: DC3.3-5V Instructions for use:Through the adjustment of the potentiometer, you can change the temperature detection threshold (i.e., control temperature value), such as the need to control the ambient temperature of 50 degrees, the module is in the corresponding ambient temperature adjusted to its green light, DO is output low level, lower than the value of this set temperature, the output of a high level, the green light does not light; module digital output D0 can be directly connected to the microcontroller, through the microcontroller to detect the high and low levels, and thus to detect the The module digital output D0 can be directly connected with microcontroller to detect the high and low levels through the microcontroller, so as to detect the temperature change of the environment; the small board digital output DO can directly drive the relay module, which can form a temperature switch to control the working temperature of the relevant equipment, and also can be connected to the fan for heat dissipation, etc.; the small board analogue output AO can be connected to the AD module through the AD converter, so that it can obtain a more accurate value of the ambient temperature. This module can also be replaced by a temperature sensor with a wire, for water temperature, water tank control.Connect VCC and GND, the module power indicator will be on, place the module on the desktop, adjust the blue potentiometer on the board until the board switching indicator is on, then adjust it back a little bit so that the switching indicator is off, and then find a way to make the temperature of the thermistor rise, at this time the module switching indicator will be on. If the temperature of the thermistor is lowered again, the switching indicator will come back to the off state. This phenomenon indicates that the ambient temperature can trigger the module, thus making the switch indicator light up. Caution:Correct wiring! Do not reverse the positive and negative connections to burn out the board electronics. Package include: According to your choice.
