LM393 voltage comparator module adjustable precision signal waveform plastic surgery high -level dual -road output LED LED

Module input voltage: 4.5-28V

Module size: 39.5mm wide 17mm

Comparison chip: LM393 comparative chip

Module sensor can connect many sensors

like:

Pightning sensor: NTC -like thermistor -type temperature sensor photosensitive resistance light -sensitive sensor vibration sensor, etc.!

How to use: The reference voltage regulating potentiometer is adjusted to generate the benchmark voltage, and the sensor is compared with the voltage generated by the voltage resistance and the benchmark voltage generated by the voltage resistance.

At the same time, the store has been redesigned to achieve a large -power load on the basis of the original height level output, which increases the large -current drive output port of the road, can realize direct drive relay, optocoupler, LED, and bee tweezers.It brings a lot of convenience to friends!

Note: The valid range of the threshold voltage is 0- (the power supply voltage is reduced by 1V).For example, 5V power supply, the validity value of the benchmark threshold voltage is 0-4V, which can achieve a comparative output.If the threshold voltage is greater than 4V in the case of 5V power supply, the output will keep the low level equal to no output.
