Each mode supports three different resolution modes. In one-time measurement mode, the sensor measures the ambient light value once, and then it goes to power down mode. In continuous measurement mode, the sensor continuously measures ambient light values. The sensor supports two different measurement modes: continuous measurement mode, and one-time measurement mode. The influence of infrared is very small.It is possible to select 2 different I2 C slave addresses.50Hz / 60Hz Light noise reject-function.Spectral responsibility is approximately human eye response.Here’s a list of the BH1750 sensor features. It can measure a minimum of 1 lux and a maximum of 65535 lux. It outputs luminosity measurements in lux. The BH1750 is a 16-bit ambient light sensor that communicates via the I2C protocol. Let’s look at the specifications of the sensor itself. Not only that, they provide very good accuracy too. BH1750 is pretty cheap and easy to interface with. For the ambient light sensor, we have selected the popular BH1750 sensor. We will later use this sensor for automatic brightness adjustment.
#AMBIENT LIGHT HOW TO#
SparkFun MAX3010X Pulse and Proximity Sensor Library Interfacing Ambient Light Sensorįirst, let’s look at how to interface the ambient light sensor. Once it’s done let’s move forward with the interface. For display, you must use the attached TFT_eSPI library. If you have already installed them, you don’t need to do the previous step except for the display library.

Download them and extract them to the library folder in the Arduino document folder. Prerequisites – Installing Necessary LibrariesĪll the required libraries are provided in the GitHub repository given below the article. We will be looking at interfacing each of these modules separately. In this part, we will be looking at how to interface some sensors to our smartwatch and will be interfacing the BH1750 ambient light sensor and the MAX30102 Heart rate sensor. In the last part, DIY Smartwatch using ESP32, we have looked at how to make some interesting watch faces for our smartwatch project.
