Arduino read this value using its internal analog to digital converter (ADC). When the temperature exceeds 30°C the fan starts rotating. LM35 TEMPERATURE SENSOR AND ARDUINO . The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The Arduino is capable of sensing its environment by receiving an input from a variety of sensors and perform some sort of an output. 1 × DS18B20 temperature sensor that is going to be soldered to the project board for airtemp 1 × ADS1115 16bit ADC to convert the analog signal from the PH sensor to digital 1 × DC to DC voltage converter to handle the required 5v for the PH sensor (the ESP8266 is 3.3v) The pulse sensor can also detect body temperature. The outputs of all the three parameters are fed to micro- controller. Unlike analog temperature sensors, calculations are performed by the sensor, and the output is an actual temperature value. The Temperature Sensor LM35 series are precision integrated-circuit temperature devices with an output voltage linearly proportional to the Centigrade temperature. A digital thermometer is a good choice of project for beginners who just stepped in to the world of microcontrollers because it provides an opportunity to learn using sensors to measure the real world signals that are analog in nature. The sensor can measure a fairly wide range of temperature (-50°C to 125°C), is fairly precise (0.1°C resolution), and is very low cost, making it a popular choice. Tweet.
