The Honeywell HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as low cost compassing and magnetometry. The HMC5883L includes our state-of-theart,…
The MLX90614 is a non-contact infrared thermometer with a measurement range from -70 to +380 degree Celsius. Just connect the four leads to your Wemos and you will have a accurate thermometer with a resolution of 0.01 and a accuracy of 0.5…
MCP9808 digital temperature sensor example The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy. The MCP9808 comes with user-programmable registers that provide…
The bmp180 from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins. The BMP180…
In this example we will expand on our SHT 31 example - Linkit One and a SHT31 temperature and humidity sensors and we will output the temperature and humidiity on a web page The layout is the same as previous Layout Code This example uses…
SHT31 is the next generation of Sensirion’s temperature and humidity sensors. It builds on a new CMOSens® sensor chip that is at the heart of Sensirion’s new humidity and temperatureplatform. The SHT3x-DIS has increased intelligence,…
In our previous LM35 example we simply displayed the temperature via the serial port but lets take it a bit further and display some temperature readings on a web page. First of all the Linkit One comes with various aerials that you can…
In this example we will connect an LM35 temperature sensor to our Linkit One The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The…
LinkIt ONE is an open-source, high-performance 8-in-1 wireless development board, based on the world's leading wearable SOC - MediaTek Aster (MT2502A) processor. LinkIt ONE integrates a high-performance Wi-Fi (MT5931) and GPS (MT3332) x…
In this example we will connect a DHT11 to a Node MCU v1.0 (you could use any ESP8266 board) board and we will display the temperature and humidity readings on a web page. The web page updates every 5 seconds I wouldn't recommend changing…
