IoT Based Temperature Sensor
Using MCP9701A sensor
Temperature sensor that helps detecting environment temperature and any variations and communicate it with servers. It uses the MCP9701A sensor for measurement and works on LoRaWAN®
The MCP9701/9701A family of Linear Active Thermistor™ Integrated Circuit (IC) is an analogue temperature sensor that converts temperature to an analogue voltage.
It’s a low-cost, low-power sensor with an accuracy of ±2°C from 0°C to +70°C (MCP9701A) ±4°C from 0°C to +70°C (MCP9701) while consuming 6 μA (typical) operating current.
