In this example we look at the CJMCU-0401, this is the module in question its a 4-bit Button Capacitive Touch Proximity Sensor With Self-locking Function Description: CJMCU-0401 is a touch IC designed with capacitive sensing principle. Its stable sensing method …

I have used many temperature sensors in my time using Arduino’s and other microcontrollers, in this article let’s look at some of the options that are available, we will also have links to example code or articles of the sensors …

I was recently asked to recommend a variety of arduino shields and boards for someone who wished to start learning but with a budget of only $30. Here are the boards and modules that I picked then I will explain …

VEML6040 color sensor senses red, green, blue, and white light and incorporates photodiodes, amplifiers, and analog / digital circuits into a single chip using CMOS process. With the color sensor applied, the brightness, and color temperature of backlight can be …

The VEML6075 senses UVA and UVB light and incorporates photodiode, amplifiers, and analog / digital circuits into a single chip using a CMOS process. When the UV sensor is applied, it is able to detect UVA and UVB intensity to …

Did you know that you can read the temperature from a DS3231 RTC – the DS3231 uses temperature compensation to calibrate the adjustable capacitors of its resonance circuit, in order to maintain time and date with accuracy The DS3231 is a …

We have just written an ebook and published it on the Amazon Kindle store, the topic of this ebook was looking at a variety of sensors with the Arduino IDE We have written this on the basis that you have …

I recently started looking through various shields I had no articles, code or tutorials for and came across a 2.8 Inch TFT LCD Shield Touch Display Screen Module For Arduino Its a cracking display, here are some pictures of it …

In this example we connect a PAJ7620 gesture sensor to an Arduino Uno The PAJ7620 integrates gesture recognition function with general I2C interface into a single chip forming an image analytic sensor system. It can recognize 9 human hand gesticulations such …

Another sensor reaches the desk, this time it is a Si1145 sensor, we will connect it to an Arduino and test it out First the sensor The Si1145/46/47 is a low-power, reflectance-based, infrared proximity, ultraviolet (UV) index, and ambient light …

In this article we look at the TMP102 digital sensor and we will connect it up to an Arduino – lets start with some technical info about this sensor The TMP102 device is a digital temperature sensor ideal for NTC/PTC …

In this article we look at the MPU-9255 and an Arduino, lets look at some information about the sensor MPU-9255 is a multi-chip module (MCM) consisting of two dies integrated into a single QFN package. One die houses the 3-Axis gyroscope …
