Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...

This is an updated 2023 tutorial on how to make a temperature and humidity sensor using an Elegoo Uno R3 Arduino. To do this, we will need the following parts: - LCD display - Breadboard - ...

The DHT22 temperature and humidity sensor is a versatile and cost-effective sensor used to measure ambient temperature and humidity for a wide range of applications. It is based on a digital signal ...

Arduino Uno: The microcontroller that will process the data from the DHT11 sensor. DHT11 Sensor: A digital sensor capable of measuring temperature in the range of 0°C to 50°C with an accuracy of ±2°C, ...

The ‘TRIG’ and ‘ECHO’ pin can be connected to any of the Arduino’s Digital pins. For now, I’m connecting ‘TRIG’ to Digital pin no. 12 and the ‘ECHO’ to pin no. 11.

The reason 4.7 kohm was chosen is because that means the sensor has to draw 1 mA through your resistors to go from 5V down to 0 V. Changing it to 2 kohms means the sensor has to pull 2.5 mA.

Arduino is the go to board for most folks looking for an introduction to microcontrollers. That's largely thanks to its sizable community, ease of use and surprising versatility. But, there is one ...
