In many of the sensor applications the output signal is too small to be registered so that the signal is to be amplified so that the microcontroller you are using can read the status of the output. This is a LM358 based signal amplifier module which can provide amplification of about 100 times. This can be used very easily as it has header pins which you can connect directly to your development board you are using with the help of a jumper wire and crocodile clip jumpers. It also has a onboard power indicator which you can use to debug and identify the state of operation. This module is particularly useful with Pressure sensors where very small changes in diaphragm’s movement has to be measured or in piezoelectric sensors etc.

Specifications

• Easy to use and reliable
• Onboard potentiometer for changing the amplification
• Power indicator LEDs
• Maximum gain 100
• Single supply for two op-amps enables reliable operation

Product Description

To use this module power the device with VCC pin with a voltage 5-12Vdc. Connect the signal output from the sensor to the Sig. Input pin of the module and take the amplified output from the Sig. Out pin. You can adjust the amplification with the help of the onboard potentiometer.
