ITEM NAME:LM393 4.5-28V Voltage Comparator Module High Level Output with Indicator A#S Product Description Description: LM393 4.5-28V Voltage Comparator Module Signal Waveform Adjustable Dual Channel High Level Output Comparator Control with Indicator Description: LM393 general single power supply comparator module. Realizes the precise linear adjustment of voltage. Realizes the double output of high low level and load drive. Facilitates the acquisition of front-end and single-chip device switch quantity. Module input voltage: 4.5-28V Module size: 39x17x10mm/1.54x0.67x0.39'' Packaging weight: 4g Comparator chip: LM393 comparator chip Module sensor can be connected to many sensors. Such as: resistive sensor: NTC thermistor type temperature sensor, photoresistive photosensor, vibration sensor, etc. How to use: Reference voltage and adjust potentiometer, adjust to generate reference voltage. Comparison of voltage and reference voltage produced by sensor and partial voltage resistance. To achieve a high and low level of comparison result output. Note: The effective range of threshold voltage is 0-(power supply voltage -1V). For example, 5V power supply, the reference threshold voltage effective value is 0-4V, can achieve comparative output. If the threshold voltage is greater than 4V in the case of 5V power supply, the output will remain low level, equals to no output. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-3mm measuring deviation due to manual measurement. Included: 1 x LM393 Voltage Comparator Module.Comparator chip: LM393 comparator chip. Facilitates the acquisition of front-end and single-chip device switch quantity. Module sensor can be connected to many sensors. Such as: resistive sensor: NTC thermistor type temperature sensor, photoresistive photosensor, vibration sensor, etc.
