Even before the COVID-19 lockdown, people spent most of their time indoors (around 90% according to some studies), so it’s important to monitor air quality and other metrics like light and sound levels in our homes, workplaces, schools, cars, etc… Metriful Sense indoor environment monitor does just that by reporting multiple metrics such as temperature, humidity, particle concentration, etc… over I2C to microcontroller or processor boards such as Arduino or Raspberry Pi. Sense hardware specifications: MCU – STMicro STM32G071KB Arm Cortex-M0+ microcontroller @ 64 MHz with 128 KB Flash, 36 KB SRAM Sensors Bosch Sensortec BME680 4-in-1 air quality sensor with relative humidity, barometric pressure, ambient temperature, and gas (VOC). Vishay VEML6030 ambient light sensor Knowles SPH0645LM4H-B MEMS microphone Optional – Shinyei PPD42 particle sensor unit I/Os – 10-pin unpopulated header with air particles sensor input, light and sound interrupt outputs, I2C, VPU pin for 3.3V/5V selection, GND, VDD, VIN […]
