LDR Photosensitive Resistance Sensor Module LM393 Comparator 3 Pin for Arduino

Description

Description:

For detecting brightness of light, apply to light brightness sensor and intelligent car

Due to output of comparator, signal is clean, waveforms and drive power are good, more than 15mA

Adjustable potentiometer can be used for adjusting the light intensity detected

A fixed bolt hole for easy installation

Using a wide voltage comparator LM393

Specification:

Size: Approx. 35 ×14 ×3 mm/ 13.78 ×5.51 ×1.18 inch

Working Voltage: 3.3V-5V

Output Form: DO digital switching outputs (0 and 1) and AO analog voltage output

1. Photoresistor module is the most sensitive to ambient light, so generally used to detect brightness of ambient light, trigger or relay modules, and microcontroller.

2. When light brightness of ambient is less than the set threshold, DO-side output is high, when light brightness of ambient is over the threshold, DO-ended output is low.

3. DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, to detect changes of environment in light intensity.

4. DO outputs can directly drive the shop relay module, which can form a light control switch.
