Here the addition of 2N3906 transistor controls an electro-magnetic relay (RL1) for driving high-current/high voltage loads like water pump motors through its N/C contacts (when soil is wet, relay ...

Mengukur tingkat kelembapan tanah menggunakan Capacitive Soil Moisture Sensor dengan menggunakan relay untuk mengatur pompa air sesuai dengan level kelembapan tanah yang telah ditentukan - kazehaya ...

const char* password = "Kukucyakuc1!"; // Replace with your Wi-Fi password // Pin definitions #define RELAY_PIN 4 // ESP32 pin GPIO4 that connects to the relay #define MOISTURE_PIN 36 // ESP32 pin ...

Watering Logic: If the soil moisture level drops below a set threshold, the water pump is activated via the relay module, and it waters the plant until the moisture reaches an acceptable level. Light ...

With this setup, the Raspberry Pi is used to control and monitor the connected components, which include a capacitive soil moisture sensor, a relay module, a micro submersible mini water pump, and ...

Using an Arduino, a moisture sensor, an LED matrix, and a few other parts, dr.mcc's build monitors the moisture level in a pot of soil and then lets you know when the plant needs water by ...

The sensor is based on an STM32 microcontroller, in this case one specifically optimized for low-power applications. The other low-power key to this build is the small seven-segment e-ink display.

The sensor is delivered temperature compensated and calibrated and a test board with analog (zero to 10 V) outputs is also available for evaluation purposes. Key specifications include: Continuous ...
