TIAO Smart Sprinkler Pi
The TIAO Smart Sprinkler Pi (TSSPi) is a piece of hardware controls your irrigation systems. It replaces your traditional sprinkler controller. TSSPi has many benefits over the traditional sprinkler controller:
- Web interface - program the watering schedule using your PC or mobile phone
- Supports complicate watering schedules
- Unlimited watering schedules
- Allow seasonal adjustments
- Weather API access - automatically adjust watering amount/time by checking online weather forecast (rain/wind etc)
- Control your sprinkler stations from anywhere in the world
- Software supports unlimited stations
- Total of 16 stations (or 1 master station + 15 stations), can expend to unlimited stations using our extension board
- Software supports unlimited stations
- Supports rain sensor
- Open source software - which means you can add your own function to the controller!
- System ON/OFF hardware switch
- Status LEDs (power, Pi power, system on, system running)
- Low cost! It's cheaper than the traditional sprinkler controller!
TSSPi Hardware Dimensions
The board dimension of TSSPi is 122.5 x 87mm, or 48.2 x 34.2 inch. It also has 4 mounting holes, the radius of the mounting hole is 2mm:
TSSPi Connector Layouts
The following picture shows the connector layout of the TSSPi. You can plug the Raspberry pi directly on top of TSSPi without using any wires. It also has two mounting holes so you can mount the Raspberry Pi on the TSSPi.
