Data Collection Node Hardware
Requirements
Requirements for the data collection node hardware:
- Wall power (no battery needed)
- Low cost
- WiFi capable comms to the gateway
- Single board with features to support all sensors
- No OS to manage
Hardware Evaluation
The following boards are candidates for data collection node hardware:
| Board | Cost | RAM | Flash/SRAM | Net | IO | Dev Tools |
|---|---|---|---|---|---|---|
| Sparkfun ESP8266 Thing | $18.50 | 32k inst/80k data | 4MB | 802.11 pnp | micro USB 32 GPIO I2C SPI UART | Arduino IDE |
| Raspberry Pi Pico W | $6.00 | 256k | 2MB | 802.11g | micro USB (host+dev) 26 GPIO 2 SPI 2 I2C 2 UART 3×12 ADC | RPI Linux |
