Maintenance-free operation with a single coin-cell battery for more than a year
This is an introduction to the reference design of a modular "CO₂ Sensor Beacon" that can be operated with a single coin-cell battery using a CO₂ sensor Senseair Sunrise.
By using the application note, schematic, BOM, Gerber files, receiver software, etc., modular designs can be advanced quickly.
A compactly constructed IoT gas sensor network
CO₂ sensor Senseair Sunrise and the temperature/humidity sensor data are transmitted using Bluetooth® Low Energy transmitter IC AK1595A . With a transmission period of 15 minutes, the average current consumption of the entire sensor beacon is only 19[μA], so one coin-cell battery can operate for more than a year.
Its compact size (25 x 45 x t22[mm]) provides high flexibility in placement. CO₂ Sensor Beacon is the optimal sensor node for building IoT sensor networks. In addition, up to eight sensor data can be acquired simultaneously by using the receiver software.
