Use:Temperature detection, temperature control sensor, environmental temperature detectionModule te color:1 、 adopt NTC thermistor sensor, sensitivity is good2 、 comparator output, clean signal, good waveform, driving ability, more than 15mA.3 、 adjust the temperature detection threshold with potentiometer4 、 working voltage Three3V-5V5, output form: DO digital switch output (0 and 1) and AO analog voltage output6, with fixed bolt hole, easy installation7, small size: 3.2cm x 1.4cm PCB8 、 use wide voltage LM393 comparator

Module instructions1. The thermistor module is sensitive to the ambient temperature and is used to detect the temperature of the surrounding environment;2, through the regulation of the potentiometer, can change the temperature detection threshold (i.e. temperature control value), such as the need to control the temperature of 50 degrees, the module in the corresponding environmental temperature to the green light, DO output low, lower than the set temperature, high output, green light;3, DO output can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, thereby testing the environment changes in temperature;4, DO output can directly drive our relay module, which can form a temperature control switch, control the working temperature of related equipment, can also be used to cool the fan;5 、 the temperature detection range of this module is 20-80 degrees celsius;6, this module can also be replaced with a wired temperature sensor for water temperature, water tank and other control

7, small analog output AO can be connected to our AD module, through the AD conversion, can obtain more accurate numerical temperature
