Gravity: Capacitive Soil Moisture Sensor is ideal for environmental science courses and indoor gardening applications. Operating within a voltage range of 3.3 to 5.5V, this sensor provides an analog output of 1.2 to 2.5V, making it compatible with low-voltage MCUs, including both 3.3V and 5V logic systems, allowing for easy integration with popular platforms such as Arduino and Raspberry Pi. It features a waterproof detection area, effectively measuring soil moisture levels while resisting corrosion for reliable performance in outdoor and controlled environments. The capacitive design offers 2-3 times the lifespan of resistive sensors, ensuring long-term durability and dependable monitoring.
This sensor is compatible with our 3-pin "Gravity" interface, which means it can be directly connected to the Gravity I/O Expansion Shield.For more detailed insights on selecting the most suitable sensor, refer to the guide on [How to Select the Best Soil Moisture Sensors for Agriculture and Research Lab].
The following image shows an example project - a device that notifies you when a plant needs to be watered.

Particle Photon Project 2: Annoying Soil Moisture Sensor with Photon and IFTTT Project
Never forget to water your plants again with this super annoying project. It combines visual, auditory, and textual cues that will prevent you from doing anything else until you provide your plant with much-needed hydration. A piezo buzzer constantly blares a shrill note, while a super-bright LED annoys your peripheral vision. In addition, this project will send constant texts to your phone reminding you that your plant needs to be watered. Sounds like fun, right?
