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.
In a previous post we showed how to connect a MAX 7219 7 Segment display - Espruino and MAX7219 7 segment display example . Here are some more examples Counter example This.
In the previous example using an HC-SRO4 ultrasonic sensor - Espruino and an ultrasonic distance sensor, we looked at displaying the distance to an object but just displayed this on the.
The HC-SR04 is used to measure distances by using ultrasonic sounds. It works by sending out a burst of ultrasound and listening for the echo when it bounces off of.
The PCF8574 is an 8 bits I/O port expander that uses the I2C protocol. Using this IC, you can use only the SDA and SCL pins of your Arduino board.
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 MBed supported device and you will have.
In this example we use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor. The DHT22 is better.
A light-dependent resistor is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied.
