Purpose:Temperature detection, temperature control sensor, ambient temperature sensorModule Features:1, NTC thermistor sensor, sensitivity is good2, the comparator output signal clean, good waveform, driving ability, than 15mA.3, adjust the temperature distribution position detection threshold4, the working voltage of 3.3V-5V5, the output form: DO digital switching output (0 and 1) and AO analog voltage output6, a fixed bolt hole for easy installation7, small plates PCB size: 3.2cm x 1.4cm8, using a wide voltage comparator LM393Module interface specification (4-wire)1 VCC 3.3V-5V external2 GND External GND3 DO small board switch digital output interfaces (0 and 1)4 AO small plates analog output interfaceModule Description1, the thermistor module is very sensitive to environmental temperature, generally used to detect the temperature of the surrounding environment;2, through the potentiometer adjustment, you can change the temperature detection threshold (ie, temperature control value), such as the need to control the ambient temperature is 50 degrees, the module in the corresponding ambient temperature to which the green light, DO output low When the level falls below the set temperature, the output is high, the green light is not bright;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 OUR outputs can directly drive a relay module, which can be composed of a thermostat switch, temperature control related equipment can also be connected to the cooling fan and the like;5, the temperature detection range of the module is 20 to 80 degrees Celsius;6, the module can be replaced with a line of temperature sensors for controlling water temperature, water tanks, etc.7, small plates AO analog output module can be connected and the shop AD through AD conversion, more accurate values can be obtained ambient temperature
