This project is currently work in progress. I'm waiting for the PCB's to arrive, so I don't have any detailed pictures yet.
I have the PCB's, but not much spare time :-/ I have uploaded pictures of one of the prototypes. More info to come.
All components have arrived - still waiting for the pcb's.
The RFSensor is based on the Sensebender Micro, and features various environment sensors.
The PCB is layed out to support Si1133 UV/Light sensor, Si7021 Temperature/Humidity sensor & BMP180 Pressure sensor. On the first powerup, the micro detects which sensors are populated on the PCB, so it is easy to make different configurations of the RFSensor.
Like the SenseBender Micro, it features an EEPROM for OTA updates as well as a ATSHA204A for SHA256 support.
The RFSensor is powered from a single CR2032 or CR2450 battery and is designed for a Hammond Mfg. 1551F enclosure (50x35x15mm).
