put together a Bluetooth oil tempeartue sensor that sends data to RaceChrono app. Physically the sensor fits average oil filter sandwich. The code, schematics and instructions are provided with no ...

The average analog oil temperature sensor off of ebay is used. The resistance of the sensor changes depending on the temperature. The documetation for the sensor provides resistance at 40C and 120C.

This isn’t about connecting a temperature sensor in your Arduino. ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

By Daniel Du In last post I get my first Arduino experience and tried 123D circuits, I will keep moving to try some sensors. I will start from LM35 temperature sensor, which can be used to monitor ...

The DHT11 sensor senses humidity and temperature, and sends the information to digital pin 5 of Arduino MCU, as shown in Fig. 2. From Arduino MCU, humidity and temperature values are uploaded to the ...
