We design and develop ZigBee modules and ZigBee networks based on the Renesas M16C ZigBee radio. Previously, we have used the Ember EM250 to develop the Smart Energy Profile for a large meter manufacturer in the US.
We have just completed the development of an I2C interface to a temperature/humidity sensor (HTU21D). This data was then sent back through Modbus over ZigBee (our implementation) to an acquisition and dashboarding application. The data was then made available through a web page. This web page may be shared, upon request.
We have been involved with ZigBee for over 6 years, and our specialty is in developing interface applications for end equipment. Our bid is very competitive because we already have the base application in place.
