I’ve had a number Arduino systems for some time now along with a large number of RF24 wireless modules and DHT11 humidity/temperature sensors. The idea I’ve had for some time is this:
- Arduino with a DHT11 sensor and RF24 wireless device pull then transmit data.
- Data goes to secondary hub/master Arduino using an RF24 module along with an Ethernet adapter (Wiznet 5100)
- This master hub then pushes the data to a web server containing a mysql database to log and store the information
Simple right? Wrong.
