The circuit is a combination of an Arduino UNO board, LM35 temperature sensor, and a 16×2 Hitachi compatible LCD. It will display the temperature on the LCD screen in degree F & in degree C. It can be ...

You also need to select the transistor by the type of fan that you use. In my case I used the well-known BD139 transistor and a 9V battery to provide power to the fan and transistor. The LM35 ...

The problem is the LM35 used this way can be + or – 2 degrees out adding the variances on the device and on the arduino chip. That means it can be as much as 4 degrees hotter or colder than what ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

The data logger runs from a PIC 16F88 microcontroller mounted to a circuit board. The PIC reads temperature data from a LM35 temperature sensor. This device can detect temperatures up to 140 ...
