I need a device to connect 6 Thermistors and measure temperature, Device to work on -30C degree to +70 so all Electrical component should be suitable for this range temperature, We will take care of enclosure and sensor connection. Data to be transmitted to the server shows in graph, every 10 to 15 min interval. Need a mechanism to monitor the temperature instantly if we need, to pull data. Device should work on Battery for at least 2 weeks.
