This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

The “YFS201 Hall Effect Water Flow Sensor” comes with three wires: Red/VCC (5-24V DC Input ... Now, have a look at the maths behind this Arduino Sketch. In our lab experiment, we used one YF-S201 ...

Today's post will discuss one such Sensor, the MQ-3 ... Arduino Code for Interfacing MQ-3 Gas Sensor Module The code for the Arduino MQ-3 alcohol sensor module is simple. We're simply reading the ...

hacked it in with an Arduino. The video does a wonderful job going into the details, but essentially by using an oxygen sensor with finer resolution (wide-band) and then outputting the appropriate ...

Other than that we have three pullup resistors for SCL, SDA, and SDO and one pulldown Resistor for SDI ... Now that we completely understand how the BMP280 Sensor works we can connect all the required ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor ... so whenever the toggle is turned ON (value is 1) LCD shows the message that motion is detected.

2, there are only five major components in the transmitter circuit: 1. Sensor DHT11 that has three interfacing pins: Vcc, Gnd, and Data Out. Vcc pin is given 5V supply from Arduino board and Gnd pin ...
