For my monthly maker column in Dutch newspaper “De Volkskrant”, I made a coolbox in which you can control the temperature in three separate compartments to keep craft beer at just the right temperature. The contraption I build uses three Peltier-elements to cool, an old desktop computers power source, an LCD to show both the …
Hi folks! Last few days I’ve been obsessed with the idea to make my own watch from arduino parts, but something cool I could use and say I did it myself. So I found out there was a sensor board (commonly named GY-87) which had three sensors on it: HMC5883L (compass), BMP085 (pressure, altitude, temperature) …

The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure. We will also discuss about retrieving the sensor altitude from its pressure readings. Experiment setup …

In this project, we are going to make an Arduino Temperature logger that will get the temperature value from the LM35 temperature sensor and the time from the DS3231 Real Time Clock module. Then we will store these values in the SD card file using the mini SD card Module. After that, we will access …

Here we are going to make a temperature controlled DC fan. DHT22 sensor is used to sense the room temperature and then we adjust speed of a DC fan/motor accordingly using PWM (Pulse Width Modulation). Arduino Uno is the heart of this project and a L293D driver IC is used to drive the DC fan/motor. Components Required …
The working voltage of this system is DC5V. It can measure the current temperature, humidity and smoke. It can display real-time data by the 1602 LCD and can realize the sound and light alarm when in the dangerous temperature and humidity. It is a simply and easily to operate monitoring alarm system about temperature humidity …

Para quem pratica este hobby sabe que a temperatura do motor é muito importante, não só para o desempenho mas também para garantir o bom funcionamento e durabilidade do motor. Ele regista a temperatura do motor do meu helicóptero durante o voo 2 vezes por segundo e armazena-a na memoria. This circuit is a small …
Humidity and Temperature are very common parameters for measuring at many places like farm, green house, medical, industries home and offices. We have already covered Humidity and Temperature Measurement using Arduino and displayed the data on LCD. In this IoT project we are going to Monitor Humidity and Temperature over the internet using ThingSpeak where we will show …

Even the actual series like SHT1x and SHT2x belong to a top in this segment. Forthcoming series SHT3x (SHT30, SHT31 and soon also SHT35) addresses mainly those of you, requiring maximum accuracy even in limit values (humidity below 10% and above 90%), miniature dimensions and ultra low power consumption. So a main difference of a …
Even the humidity & temperature sensors can be „3G“ Continue Reading
Company MEC, Dutch producer of top-class push-button switches Multimec, Unimec and others comes with good news for developers and producers of electronics. Well-known reliable push-buttons were in majority of cases available in so called standard version (L6, -40…+115°C) and in a high-temperature version (H9, -40…+160°C). From now on, all types will be gradually available only …
High-temperature versions of MEC switches now for the price of standard versions. Continue Reading
