After covering the basic raspberry pi tutorials in previous articles, in this project we are designing first application based on the previous tutorials. The first basic application is a Raspberry Pi Temperature Monitor where you can monitor the temperature readings on computer. For this we have interfaced Raspberry Pi with LM35. You can learn more about LM35 temperature sensor, here
As discussed in previous tutorials, there are no ADC channels provided internally in Raspberry Pi. So if we want to interface any analog sensors we need an ADC conversion unit. And in one of our tutorials we have Interfaced ADC0804 chip to Raspberry Pi to read an analog value. So go through it before building this Room Temperature Thermometer.
