Things used in this project

Hardware components

Thingy:91 Multi-sensor cellular IoT Prototyping Platform
Nordic Semiconductor Thingy:91 Multi-sensor cellular IoT Prototyping Platform
At least two, one for a sensor and one for an actuator. You can have multiple sensors and actuators running for this project (We do at least!)
×2
Irritol RainSensor Series RS500
Optional for sensor program. We used the RS500 model, which is the only wired one
×1
Capacitive Soil Moisture Sensor
Optional for sensor program.
×1
24VAC 40VA Plug in Transformer
Required for actuator program.
×1
Irritrol 2400S Control Valve
Required for actuator program. Any valve would work, just ensure it works with the transformer you use.
×1
SPST 5V Relay
required for actuator program.
×1
Ceramic Disc Capacitor, 0.1 µF
Ceramic Disc Capacitor, 0.1 µF
required for actuator program.
×2
Arduino UNO
