This project uses a Particle Electron and a SHT-10 based soil temperature and moisture sensor to remotely monitor the health of your garden/farm. The sensor provides a 4.5% moisture and 0.5% temperature measurement accuracy. You can set it up to alert you via SMS, email or an iOS notification.
Things you'll need:
- Particle Electron
- Breadboard or Protoboard
- Particle Solar Shield (optional)
- LiPo battery or a USB power source
The setup is very simple. The SHT-10 sensor uses two pins to clock out the data and operates from a 3.3V power source.
- SHT_RED -- Electron_3V3
- SHT_BLACK -- Electron_GND
- SHT_YELLOW_CLOCK -- Electron_D1
- SHT_GREEN_DATA -- Electron_D0
Ideally you would mount this project in a weather-proof enclosure, but for the sake of simplicity, the picture shows the breadboard right in the soil (don't try this at home).
You can change the threshold of the moisture and temperature limits in the firmware to raise an alert. These limits will be based on your soil and plant type.
