4 Channel relay Module compatible with arduino
Relays are always good to have especially for electronics projects. Relay itself offers two main benefits:
- Isolation of low voltage system against high voltage system, example 5VDC and 240VAC
- Allow electronics with low voltage to control high power load, example from Arduino to AC light bulb.

Photosensitive Sensor Module (LDR sensor module)
RM5.00The Light sensor module comes with the basic components for light detection. Supplying power and it is good to be used. Use it to detect the light brightness in your environment and decide to switch OFF or ON light. Or maybe adjust the brightness of the LED for your house? It comes with digital and analog output. You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is a digital output, so you will know if the light is presented and decide what to do with it. Check the schematic for more details.
