Functional Description

Overview

As going by the word “mono” & “Zero”, monoZero represents monoZ`s first thing in IoT space. monoZero is a compact and powerful cellular connectivity enabled development kit loaded with several peripherals allowing users to easily connect and control their sensors or other devices. This board is an add-on board of the monoZero ecosystem and can be configured with monoZ: SDK libraries to reduce go to market time.monoZero Sensor variant hosts several industrial grade sensors over UART, SPI, I2C, GPIO peripherals to support various environmental monitoring applications.

Features

• Plug and play design and stacked on the connectivity board
• Variety of industrial grade sensors including ambient light sensor, CO2 sensor, gyroscope, accelerometer, magnetometer, temperature, humidity and pressure sensors

Board layout

• Connector-J4 - 40 pin connector
• Ambient Light Sensor - To measure optical energy - at specific wavelengths or specific bands of wavelength on the light spectrum
• CO2 Sensor - Detects the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength
• Connector-J3 - 40 pin connector
• DIP Switch - It allows the user to quickly toggle the device between a variety of operating modes
• Gyroscope & Accelerometer Sensor - It senses angular rotational velocity, acceleration of the object and Magnetometer sensor represents the magnetic field around XYZ-axis
• Temperature & Humidity Sensor - It measures the gas,temperature,pressure and humidity of its environment

DIP switch

DIP switch is used in monoZ Sensor Addon Board to enable or disable the interrupt pins viz GYRO_INT1, GYRO_INT2, ACCEL_INT1, ACCEL_INT2, MAGT_INT, MAGT_DATA_RDY which are connected to Gyroscope, Accelerometer and Magnetometer sensor.

• To operate these sensors in interrupt mode,corresponding switches are to be made on
• To operate these sensors in poll mode,corresponding switches are to be off
