Dear Sir or Madam, I am looking to buy high end wireless sensors that can be integrated into our online building management system. The sensors would need to be able to monitor the following; temperature, gas, electricity, humidity etc via mobile data/wireless lan. These sensors would then upload to the cloud where our system imports the info. These sensors would need to give real-time readings and have an option for power and battery operation.

G'day, I'm an Electronics R&D Engineer based in Sydney ? Whear abouts are you lcoated ? I have 25+ years experiance in desiging products from idea throught to manuacturing, (even had our own electronics PCB Assembly company in Southwest Sydney a few years back now) Would you be interested in having something custom designed and made specifically for your building automation system? If so, I'd quite like the opportunity to design/make what ever you need. Temperature sensors, power meters, all wirelss, all running on 802.15.4 / Zigbee, or if you wanted WiFi, or B/T for the wirelss comms, then thats all fine as well... we can design the electronics and the casing, provide a prototype, and do mass production... My bid is just an arbitary value, but lets chat and I can revise to whatever you need... I quite look forward to chatting about your project. PS, I spent 5 years of my electrical aprenticeship(so to speak) in building automation of air conditioning of multistorey building, so I am quite familair in this entire control systems area as well PPS, I will be away form friday for teh long weekend, but hope to chat Tuesday when I am back on deck Cheers, Darren

Hello! Me and my friends (we're all embedded engineers) can successfully integrate wireless sensors in your online building management system. We can develop own sensors, which can monitor a bunch of params: temperature, gas, electricity, humidity and transmit collected data via mobile data/wireless lan. These sensors, certainly, will have choice of power source and can operate from battery. First of all we need detailed specification. Then we proceed to design and later to programming, prototype creation and tests. After all we deliver your fully functional product, ready to use. It's our view of the entire process. If interested, drop me a note. Regards, Vitaliy and Friends
