APC1 Terminal Click Bundle

HOW DOES IT WORK?

The ScioSense APC1 sensor emerges as a game-changer in air quality sensing. It is a compact, all-in-one environmental monitoring solution designed to measure various air quality parameters precisely. These include particulate matter (PM) levels as small as 0.3µm, aerosols, volatile organic compounds (VOCs), equivalent CO2 (eCO2), temperature, and humidity. What sets the APC1 apart is its calibration accuracy, ensuring that the data it provides meets international standards for metrics such as PM1.0, PM2.5, PM10, Total Volatile Organic Compounds (TVOC), equivalent CO2 (eCO2), and Air Quality Index (AQI). This bundle comes with a J version of the APC1 sensor, which uses an I2C serial interface, while the U version is for UART.

Combining the APC1 sensor with the Terminal Click board™ opens up a world of possibilities for creating a robust air quality monitoring system. This integration simplifies the process of interfacing the sensor with a microcontroller (MCU) for data processing and display. The Terminal Click board™ acts as an intermediary, allowing users to harness and leverage the sensor’s data for many applications.

With its precision and comprehensive parameter measurements, this bundle suits various applications, from ensuring healthier indoor environments to contributing to vital air quality research initiatives. By combining cutting-edge sensor technology with user-friendly interfacing, you can transform how you monitor and respond to air quality conditions, making the world safer and healthier.

We provide a library for the APC1 Sensor Demo as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for APC1 Sensor Demo driver.

Key functions

• apc1sensor_start_measurement This function starts measurement by setting the device to measurement mode.

• apc1sensor_read_info This function reads the device name, serial number, and firmware version.

• apc1sensor_read_measurement This function reads the measurement 64-bytes output structure data.

Example Description

This example demonstrates the use of APC1 Air Quality Sensor Bundle by reading measurement results (PM1.0, PM2.5, PM10, TVOC, eCO2, AQI, temperature, relative humidity, etc.).
