Wireless temperature sensor

Projects General Guidance
1

Hi everyone!

I have a big project I am working on and I am looking for some guidance anyone might have to offer. Basically, I am working on a device that needs face temperature as an input measurement. I am looking to measure face temperature overnight and then collect the data to process it and integrate it with other sensors. I want to explore the possibility of having the sensor be wireless to the Arduino, since any wires could get entangled overnight and choke me.
Is this possible with Arduino? Do you have an idea of which temperature sensor to use? It should be able to measure about 1 C of precision. Budget is not a problem.

Any help will be GREALTY appreciated.
Also, this is for a school project!

Thank you and have a great day!

I think you should look at the ESP-01 rather than an Arduino. It is made with this sort of thing in mind. It has the intelligence to work with a DS18B20 temp sensor and send regular readings via WiFi to a master Arduino, or direct a PC, where they are recorded.

The ESP-01 with a CR2032 battery would work for this even though the battery is 3V and the ESP wants 3.3V. For a sensor I would use the DS18B20.

You have couple of option depending on their availability ,

  1. can use NRF24L01 RF transmitter and receiver
  2. OR can use WIFI as exchange of data, maybe NODEMCU
