Description

Experience Level: Intermediate
We currently require electronics hardware / software development. The project involves the circuit design and PCB layout, the plastic enclosures have already been specified. The product is a humidity, temperature, lux level monitor for buildings, briefly the details are, battery powered and wirelessly transfer temperature, humidity and lux level readings. The hardware would include a ZigBee Telegesis module, serially communicating with a PIC24F16KA102 that interfaces via an SPI bus to a Sensirion temperature / humidity sensor (http://www.sensirion.com/en/pdf/product_information/Datasheet-humidity-sensor-SHT7x.pdf). The lux level IC is still to be selected. The PIC needs be in its lowest powered sleep mode and wake up at a predefined interval, read the sensor values, send then to the Telegesis module via the serial interface and then resume sleeping.

There are a few other very basic features and I can send you the full specification, state flow diagram if you are interested in quoting for this project.
