Singapore Indoor Farms IoT Showcase
Raspberry Pi rig with DHT22 humidity, a CO2 sensor, and relay-driven control of the grow lights and water pump. One demo rack deployed at their facility on the west coast. Featured on Channel News Asia in May 2022.
Context
Singapore Indoor Farms wanted a small visible IoT rig they could show clients walking through their facility. One demo rack on their floor to prove the data path end-to-end and let visitors see live readings.
It was a W2 freelance gig during my SP IoT internship era. The scope was deliberately narrow: prove the loop works, show numbers on a screen, let an operator flip a relay.
Stack
- One Raspberry Pi at the rack. GPIO wired to a DHT22 humidity sensor and a separate CO2 sensor.
- Raspberry Pi camera for visual monitoring of the rack.
- Relays off the Pi GPIO to switch the grow lights and the water pump on and off.
- A monitoring view so the operator could observe readings and trigger simple notifications.
What it did for the customer
The rig was primarily a sales tool. The farm's team used it to walk clients through what data-driven indoor agriculture looks like. CNA picked it up in May 2022 as a Singapore Indoor Farms feature.
