Connections. Arduino Uno has a set of Analog input pins which can are used to take analog input signals from a sensor. Remember there are two types of signals: 1. Digital Signals: These signals have only two values 1 or 0 (on or off). 2. Analog Signals: These signals have values in a range.
· How does CAN BUS works? The fuel level, door sensors, odometer, and many more parts of a car have to communicate with each other some how, and CAN BUS is what they used to do that. These CAN compatible components, which are called “nodes” are connected with a 3-string copper wires, with no central router to govern the flow of data. Every node can hear the messages of every …
· yassin: RLOAD 10000 is for 1oK Load Resistor! As clearly pointed in this post, while using the “MQ-135” library-supported Arduino setup, the gas sensor calibration can be done at by finding the value of Ro in fresh air, and then using that value to find Rs through the formula: Rs = (Vcc/VRL-1)x RL, that means Rs = (5V/(sensorValue * (/))-1)*RL.
There are different water sensors used for water level sensing and water flow rate sensing. Line follower sensor : This sensor type is used to track the line. It can track white line in black background or black line in white background depending upon programming and use of sensors on the arduino board. Motion sensor
