Communications: B1/B3/B5/B8/B20/B28 LTE NB-IoT M2M module Or SIM800C

Pimoroni VL53L1X Time of Flight (ToF) Sensor Breakout

LIDAR distance Sensor (occupancy)

BNO055 Absolute Orientation

Product Feature The BNO055 combines a wide range of sensors, including 3-axis 12-bit accelerometers, 3-axis geomagnetic sensors and 3-axis 16-bit gyroscopes, with built-in Atmel 32-bit MCUs to handle software operations between various sensors. Single data of three types of sensors (acceleration/geomagnetic/gyro) can be provided separately, and combined data can be provided. Through the built-in MCU calculation, more application support can be provided for products such as smart phones and wearable devices. Product Parameter Using the chip: BNO055 Power supply: 3-5v (internal low dropout voltage regulation) Communication method: standard IIC/serial communication protocol Module size 12mm*20mm Schematic: https://ae01.alicdn.com/kf/HTB16GZfajzuK1RjSsppq6xz0XXaE.jpg

Story

Park-Box

Thesolution provides via Cloud Web Server an insight into the real time demographics (affluence, Age, Gender, emotion) of urban gym park users combined with the total hours of use of each individual park machine, so official and civic organizations can better understand its audience, pike-hours, and total use of spaces to better interact, plan and enhance activities inside these spaces to broaden their impact on their surrounding communities.
