Arduino CO Monitor Using MQ7 Sensor: A few words why this instructable was created: one day my girlfriend''s mother phoned us at the middle of the night because she felt really sick she had dizziness, tachycardia, nausea, high blood pressure, she even fainted for unknown time (probabl…

LM35 Temperature Sensor Arduino Tutorial (3 Examples)

+

Wiring – Connecting LM35 analog temperature sensor to Arduino. Connecting an LM35 to the Arduino is very easy as you only need to connect 3 pins. Start by connecting the +V S pin to the 5 V output of the Arduino and the GND pin to the ground. Next, connect the middle pin (V OUT) to any of the analog inputs of the Arduino. In this case, I used ...

28/10/2019· The difference between analog and digital sensors is that an analog sensor collects readings over a range of values, and a digital sensor only reads a HIGH or LOW signal (a bit of data). The Arduino has a 10bit AnalogtoDigitalConverter (ADC), which maps sensor readings between 0 and the operating voltage (5V or ) into integer values between 0 and 1023.
