Steps
- Plan the network layout with 2 sensor nodes and 1 gateway.
- Build each sensor node with an ESP32, NRF24L01 radio, and temperature, humidity, and pressure sensors.
- Program the nodes to send readings to the gateway on a set interval.
- Program the gateway to collect all readings and push them to a free cloud dashboard.
- Test range and packet loss by moving nodes farther apart.
- Screenshot the dashboard and document the network design for your portfolio.
What to photograph for your portfolio
- Network topology diagram
