Photodiode light level detection with Arduino

In today’s article, we will implement a photodiode light-level detection with Arduino UNO. We will use Arduino IDE software for coding and a ready-made photodiode module as the sensor. It is one of those modules easily obtainable in any retailer that sells Arduino stuff. What we...

Photo Diode Amplifier

This small module is a photodiode amplifier. The circuit consists of an OPAMP configured as a transimpedance amplifier for amplifying the light-dependent current of the photodiode. A small bias voltage is derived from the positive supply and applied to the op amp’s non-inverting...

Photodiode Amplifier for Visible Light Using OPA381 – Arduino Nano Shield

The project presented here is a photodiode amplifier for visible light. The output voltage of the circuit increases linearly with light intensity. Low-cost BPW34 photodiode is used as a light sensor and OPA381 op-amp as an amplifier. OPA381 is a transimpedance amplifier that converts...
