This project involves the design and prototype manufacture of three components: 1) Wireless sensor interface 2) Logger and GSM/GPRS modem 3) Server software to record and configure the sensors 1) The wireless sensor interface will be housed in an IP68 enclosure with the sensor which communicates via RS485. Power supply will be 12-24VDC. Data will be received from the sensor and sent wirelessly to the logger, commands will be received from the logger and sent to the sensor. The distance from the sensor to the modem will be less than 200m. 2) The logger will log the incoming data from the sensor and then periodically upload this via SMS/GPRS to the server. The logger will also require 2 relay(1A,240VAC)outputs and 2 isolated inputs. Commands will be relayed from the server to the sensor unit. Power supply 12-24VDC. This unit will also be required to control up to 4 sensor units. Local LCD display of sensor data (scrolling through the number of active sensor units) The sensor has a RTC for date/time stamping if required. 3) Software to tabulate and graph the sensor data. User interface to be able to send configuration commands to the sensor. Manual for the sensor will be provided, you will need to provide all other components. Prototypes do not need to be in enclosure. Although this only includes the building of 2 prototypes of each component, please indicate volume pricing for order volumes up to 100.

Hello, Looking at your project, it appears very similar to jobs I have successfully completed in the past. I've utilized off-the-shelf transmitted modules, that are already FCC-approved, which will drastically cut down any certifications you may need to undergo. Additionally, I've seen ranges in excess of 4 miles, while not bringing the cost of the device over $50. I'd expect, based on preliminary research, past experience, and contingent of the cost of the GPRS modem, for the module to cost around $100-150 in production quantity. We will have to further discuss the requirements in terms of the software for the end-user, which may affect the bid slightly. I'm additionally open to working on at an hourly rate if that is more convenient for you. Feel free to discuss this bid with me further if you wish. I am available via phone, email, IM and skype. I am based in the Northeastern US, where all work will be completed.
