As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for ...

At the base level, sensors collect real-time data on soil moisture, pH, temperature, and humidity. These are supported by microcontrollers, most notably Arduino UNO, Raspberry Pi, ESP8266, and ESP32, ...

Agriculture is a cornerstone of the Indian economy, with approximately 58% of rural households relying on it as their primary livelihood. Soil moisture is a critical factor in agriculture, affecting ...

The Plant Bot is an open-source, Internet-enabled plant monitor powered by the ESP32-C3 microcontroller and integrating a corrosion-resistant capacitive moisture soil sensor and a pump driver on a ...

Software: Arduino IDE or PlatformIO. Coding: Use the Arduino or PlatformIO libraries for ESP32 to read soil moisture data. Set thresholds for irrigation based on the data. Control the solenoid valve ...

The soil moisture sensor is inserted into the soil, and similarly, the water level sensor is submerged into the water tank. Upon powering on the device and opening the Blynk App, the ESP32 ...

Disadvantages: The electrical conductivity of soil depends not only on the water content, but also strongly on the salt content, fertilisers and soil type, and is therefore an unreliable measure of ...

The capacitive soil moisture sensors are connected to the analog to digital converter ADS1115. ADS 1115 is connected to the ESP32 via I2C pins (D21 & D22). DHT 11 is connected to pin D13, MQ135’s ...
