Temperature detection, temperature control sensor, the ambient temperature detection
The module features:
1, using the NTC thermistor sensor, sensitivity
2, the comparator output signal waveform, clean, good, strong drive ability, more than 15mA.
3, with the potentiometer adjusting temperature detection threshold
4, the working voltage of 3.3V-5V
5, the output: digital switch output (0 and 1) and analog output (voltage output)
6, a fixed bolt holes, convenient installation
7, small PCB size: 3.5cm x 1.5cm
8, the use of wide voltage comparator LM393
Module for use
1, the thermistor module is very sensitive to the environment temperature, generally used to detect the temperature of the environment;
2, through the regulation of the potentiometer, can change the temperature detectionthreshold (i.e., temperature control, such as value) environment which need to control thetemperature of 50 degrees, module in the corresponding environmental temperature to thegreen light, DO outputs high level, below the setting temperature value, high output, light is not bright;
3, the DO output can be directly connected with the SCM, through the microcontroller todetect high or low level, thereby detecting the environment temperature change;
4, the output end of the DO can directly drive the shop relay module, which can be composed of a temperature control switch, control related equipment operating temperature, also can beconnected with fan for heat dissipation;
The temperature detection range of 5, this module is 20-80 degrees celsius;
6, the module can also be replaced by a temperature sensor, with wired for temperaturecontrol water tank, etc..
