Smart Plant Monitor Project Combo | NodeMCU ESP8266 + Capacitive Soil Moisture Sensor + Buzzer

Smart Plant Monitor Project Combo — NodeMCU ESP8266 + Capacitive Soil Moisture Sensor + Buzzer

Keep your plants healthy with this Smart Plant Monitor project combo from Xsortex HUB. This kit pairs the NodeMCU ESP8266 WiFi microcontroller with a Capacitive Soil Moisture Sensor V2.0, an Active Buzzer, and a Green LED — letting you monitor soil moisture levels in real time, trigger an alert when the soil gets too dry, and even send data over WiFi to a dashboard or mobile app.

Perfect for students building an IoT agriculture project, plant lovers who want a smart watering reminder, or makers exploring ESP8266 WiFi capabilities with real-world sensor data.

What’s Included in This Combo?

• 1× NodeMCU ESP8266 (ESP-12E) — 80/160MHz, 802.11 b/g/n WiFi, 11 digital I/O, 1 analog input, Micro-USB, 3.3V logic
• 1× Capacitive Soil Moisture Sensor V2.0 — Corrosion-resistant capacitive design, analog output, 3.3V–5V compatible
• 1× 3V Active Buzzer — Audible alert when soil moisture drops below dry threshold
• 5× 5mm Green LED — Visual indicator for healthy soil moisture level
• Jumper Wires —  male-to-female for breadboard connections
• Breadboard — 400-point solderless breadboard for prototyping

How It Works

The Capacitive Soil Moisture Sensor V2.0 measures the dielectric permittivity of the soil — a more accurate and durable method than resistive sensors. The analog output is read by the NodeMCU’s ADC pin. When moisture is adequate, the green LED stays on. When the soil gets too dry, the buzzer sounds an alert. With the ESP8266’s built-in WiFi, you can extend the project to send moisture readings to Blynk, ThingSpeak, or a custom web dashboard.
