PH Sensor Module with PH Probe - Water Quality Monitoring Sensor [C] Audio Amplifier Fixing Method: Dual side grub

Fixing Method: Dual side grub screws

Connect the base terminal of the transistor to the 5V GPIO pin of the controller or V supply line of the Digital Circuit but care should be taken as it will need 120mA of base current if you are operating in high gain region

Voltage Rating: 600V

This will come handy if your machinery falls like bike crash and other accidents as it will turn off the electrical supply and thereby minimising the risk of fire by short circuiting

Drones etc where high current is involved
