Photodiode light level detection with Arduino
https://www.electronics-lab.com/project/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 want to achieve is light-level detection, so that we […]
Precision Switched Integrator Transimpedance Amplifier
https://www.electronics-lab.com/project/precision-switched-integrator-transimpedance-amplifier/
This project is based on IVC102 chip from Texas Instruments. This chip is a precision integrating amplifier with FET OPAMP, integrating capacitors, and low leakage FET switches. It integrates low-level input current for a user-determined period, storing the resulting voltage on the integrating capacitor. The output voltage can be held for accurate measurement. The IVC102 […]
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 input. This prevents the output from saturating at the negative supply rail […]
Photodiode Amplifier for Visible Light Using OPA381 – Arduino Nano Shield
https://www.electronics-lab.com/project/photo-diode-amplifier-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 photodiode current flow into voltage. The operating voltage of this circuit […]
