3V-6V DC Supply Voltage
height: 100%
5 VDC to provide input for a vast range of microcontrollers operating at different voltages
It is consists of piezoelectric element
The user can achieve a high quality of recording (for 8 to 20secs) for each application with the adjustment of the on-board resistor
Relay Module (1 Channel - 5V) 7490 3V-6V DC Supply VoltageIntroduction : It is a 1 channel relay board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other equipment with large current. used where it is necessary to control a circuit by a low power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.
