RobotDyn ESP8266-PRO connected to NRF24L01 listening to three pipes.
-
ESP8266-PRO publishes sensor values to Mosquitto server.
-
Three remote sensors connected to Arduino Pro Mini send values to ESP8266-PRO via NRF24L01.
-
Sensors go to sleep periodically and put the radio to sleep as well.
-
Sensor ID 0 is connected to a button and runs on 3 AA batteries.
-
Interrupt routine wakes up Arduino and NRF24L01 radio when button pressed.
-
Arduino and radio go back to sleep after sending message.
-
Node-RED on Raspberry Pi decides what to do with sensor messages.
-
Sensor ID 0 messages toggle IKEA Tradfri wireles outlet via CC2531 Zigbee module connected to Raspberry Pi.
Basestation with ESP8266 MQTT client and NRF24L01 receiver.
Wireless button PCB design in Fritzing.
Dollar store LED light repurposed.
Another view of the Arduino and NRF24L01. Had many connection issues with the female headers. Also many issues with power stability which required 2x 0.1uF capacitors.
Completed project. The red power LED light is covered with black tape.
Node-RED Dashboard showing the sensor values (currently just counting to 0 to 255).
Node-RED flow for the sensors.
Node-RED flow for turning IKEA Tradfri outlet on/off with auto-off feature.
