ESP32 A-19: Monitoring Plant Water Needs with Soil Moisture Sensor
Learn how to detect soil humidity and monitor your plant's water needs with the ESP32 soil moisture sensor.
00:00:00 In this tutorial, we explore the soil moisture sensor for the ESP32 board. Learn how to detect soil humidity and wire the sensor to the analog pins of the board.
🌱 The soil moisture sensor can detect whether the soil is humid or dry.
🔌 The wiring for the soil moisture sensor is simple, with the A0 pin connected to any analog to digital pin.
📊 The analog read block in the ESP32 provides a range of values from zero to 4095 for sensor readings.
00:01:12 Learn how to use the ESP32 and a soil moisture sensor to monitor your plant's water needs and control an LED accordingly.
The maximum value on the serial monitor is 4095 when the sensor is not in water, and around 2000 when it is submerged.
The speaker encourages viewers to test the sensor themselves.
The speaker plans to improve the program to turn on an LED when the planter needs water and turn it off otherwise.
00:02:20 An overview of testing the soil moisture sensor by directly booting it inside water and testing with wet and dry soil.
🌱 The ESP32 A-19 is a soil moisture sensor.
💧 The sensor can be tested with both wet and dry soil.
