Capacitive Soil moisture sensor:

A capacitive soil moisture sensor is an electronic device used to measure the moisture level in soil by detecting changes in capacitance(ability to store electriciyt). Wet soil increases capacitance, while dry soil decreases it. And i want to use this sensor because they are covered in a protective layer, making them more durable and reliable.

DHT11/DHT22 (Temperature & Humidity Sensor)

– Measures temperature and humidity inside the greenhouse.

Photo transistor

– The phototransistor detects ambient light(natural light present at that surrounding ) intensity in the greenhouse and converts it into an electrical signal.

XIAO ESP32-C3

– My microcontroller acts as the brain for this system. It processes sensor data, controls actuators, and enables wireless communication.

Water pump

– Pumps water for automated irrigation based on soil moisture levels.

DC Fan

– Provides ventilation and helps regulate temperature.

LED bulb

– Provides additional lighting when natural light is insufficient
