Using the 433MHz RF Transmitter and Receiver with Arduino
https://www.electronics-lab.com/using-433mhz-rf-transmitter-receiver-arduino/
While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where communication is one way (Receiving device cannot transmit and the transmitting device cannot receive). Several options […]
Interesting Sensors To Add To Your Weather Station Project
https://www.electronics-lab.com/interesting-sensors-to-add-to-your-weather-station-project/
A Weather station project is a project that gives you information about the weather in a particular area and is quite useful for a lot of things like planning of the day, farming and several others. A weather station project is one of those projects where you can have different types of sensors attached to it. […]
Arduino Two-Way Bluetooth Communication Tutorial
https://www.electronics-lab.com/arduino-two-way-bluetooth-communication-tutorial/
Welcome to another Arduino Tutorial! Today we are going to learn how to use Bluetooth to exchange data between two Arduino boards! As a demonstration project, we are going to build a simple weather station. There is a lot to cover so let’s get started! Arduino Two-Way Bluetooth Communication Tutorial – [Link]
DIY Data logging weather station under $15
https://www.electronics-lab.com/diy-data-logging-weather-station-15/
A Homeschoolers Workbench @ instructables.com has build an Arduino based datalogger that reads data from a DHT22 sensor and logs them on a SD card. In this instructable I am going to show you how to build a weather station that logs the information that it collects on a sd card. DIY Data logging weather […]
Wide range of Hygrometers Compared
https://www.electronics-lab.com/wide-range-hygrometers-compared/
robert @ kandrsmith.org has a detailed article comparing the most common Humidity sensors. He writes: Previous experiments looked at comparing a set of six Aosong DHT22/AM2302 and compared the Aosong DHT22/AM2302 with the Aosong DHT11 and Sensirion SHT71. Here I have added five new devices meaning this test now covers most commonly available low-cost digital […]
Adjusting clock with alarm, hygrometer & thermometer on 1.8″ ST7735 display
https://www.electronics-lab.com/adjusting-clock-alarm-hygrometer-thermometer-1-8%e2%80%b3-st7735-display/
Nicu Florica blogged about his adjusting clock with alarm, hygrometer and thermometer on 1.8″ ST7735 display: I use feature from article Another adjusting clock with alarm & thermometer using DS3231 on 1.8″ ST7735 display and change reading internal temperature of DS3231 with DHT22 sensor (AM2302), but you can use a cheaper and not very precise DHT11 […]
PWM Fan controller
https://www.electronics-lab.com/pwm-fan-controller/
Lucky Resistor has build a PWM fan controller using Arduino and DHT22 sesnsors. The fan controller described on this project page, controls one or more PWM controlled 12V PC fans. It uses the input from two precise DHT22 based temperature sensors. The MCU is an Arduino Uno, which is powered using a 12V power source. […]
Dual set point programmable thermostat
https://www.electronics-lab.com/dual-setpoint-thermostat/
Programmable thermostats are cool things. They let you set the room temperature according to your schedule and will automatically make those adjustments for you. If you use them the way they’re intended to, they could be a great way to save on home energy costs. They work perfectly for people with fixed daily schedules. You can set […]
Wireless temperature and humidity monitor for baby’s room
https://www.electronics-lab.com/wireless-temperature-humidity-monitor-babys-room/
This project describes a DIY wireless temperature and humidity monitor for kids’ or infant’s room using the Arduino platform, and inexpensive and easily available ASK transmitter/receiver modules. On the transmitting end, an Arduino nano senses the ambient room temperature and humidity using the DHT22 sensor and transmits the data to a receiving end Arduino over […]
Touch Weather Station using a DHT22 Sensor and a Raspberry Pi 3 with TKInter
https://www.electronics-lab.com/touch-weather-station-using-dht22-sensor-raspberry-pi-3-tkinter/
educ8s.tv tests the new Raspberry Pi 3 board, by building a simple but useful project. A few months back, the Raspberry Pi 3 board was released. It is a great new board because it now offers WiFi and Bluetooth connectivity out of the box! It uses a quad core processor which operates at 1.2Ghz and […]
