== Measurement System with BLE Sensor Nodes and Mobile Hub (Freelance) == | |||
Posted 30th March 2015 | |||
We are a small high-tech company (based in Cambridge) looking for a low-power, wireless measurement and data logging solution for deployment in different indoor environments. | |||
*Several wireless measurement nodes periodically transfer data to a central hub via low-energy wireless technology (BLE). <br /> Average power consumption <1mW, powered by PV module with rechargeable battery or supercapacitor. <br /> Measurements: two or more ADCs, I2C for sensors | |||
*The hub (smartphone or tablet) displays the information from all nodes and uploads it via mobile network (GSM) to a server accessible by us. | |||
