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. Some examples of similar ideas here: [login to view URL] [login to view URL] [login to view URL]

Coming to the point, I have already finished your type of project 4 months ago for Saudi client (which he named as "Wireless Health Monitoring System") The temperature, heartbeat was measured at patient and was sent wirelessly to Doctor's room where he could monitor the status in real time. In your project, there is addition of gas humidity etc. and as you said, optional battery operation as well. What I will deliver in my bid: 1- Circuit design 2- Code 3- Software simulation (in proteus software or other) 4- Free descriptive report (up to 5 pages). If needed more, I charge $10/100 words for professional writing. 5- Free support (up to 15 days) after the completion of project. What I need from you: 1- Full written description of every function you need. 2- Clearly written specifications 3- Programming language usage (if you want to specify any) 4- Microcontroller, software etc. choice (if any) Notes: 1- Building prototype is not included in the bid. However, it can be made on your demand (will charge extra for this). 2- The bid is just an estimate. Actual bid will be adjusted after you send me complete WRITTEN specifications and discuss with me.
