# Solar Cell Test Bench Project

## Overview

This project aims to develop a test bench for analyzing the voltage and current behavior of a solar cell under varying surrounding temperatures. The project is a collaborative effort between **Konstantin Sang** and **Siddhart Patel**. Konstantin is responsible for the mechanical design and literature, while Siddhart handles the electronics and programming aspects.

## Project Goal

1. **Monitoring surrounding temperature** with two DHT22 sensors.

2. **Controlling a heating element** through a relay setup.

3. **Implementing a P algorithm** for maintaining a desired temperature range, using real-time temperature feedback.

*More mini goals will be added in the future as the project progresses.*

## Current Work Steps

### Step 1: Temperature Monitoring

- Utilize two DHT22 temperature sensors to capture the ambient temperature.

- Calculate the **RMS** and **average** temperature values from both sensors to ensure a precise and stable reading.

**Status:** DONE

**Video Demonstration:**

**Library Used:**  

- [DHT Sensor Library by Adafruit](https://github.com/adafruit/DHT-sensor-library)

### Step 2: Temperature Control

- Integrate a heating element, controlled by a relay, to adjust the surrounding temperature.

- Program the microcontroller to turn the heating element on or off as needed to reach target temperatures.

**Status:** DONE

**Video Demonstration:**

### Step 3: Implementing a Control Algorithm

- Continuously monitor the **RMS** temperature and adjust the heating element's operation to minimize deviations from the target value.

- Achieve a stable environment by dynamically controlling the heating element based on real-time feedback from the sensors.

**Status:** DONE

**Video Demonstration:**

### Step 4: Sensor Testing and Integration

- Test the **ACS712 Current Sensor** with both Arduino and Raspberry Pi Pico.

- Test the **Voltage Sensor** with both Arduino and Raspberry Pi Pico.

- Combine the individual codes to create a unified script for measuring both current and voltage simultaneously.

**Status:** DONE

**Video Demonstration:**
