Summary of RICOH ELECTRONIC DEVICES COMPANY LAUNCHES THE RIOT-001 ENVIRONMENT SENSING BOARD
The RIOT-001 Environment Sensing Board transmits temperature, humidity, pressure, and light data via Bluetooth to smart devices. It efficiently harvests solar energy using a buck DC/DC converter to charge a Li-ion battery, which is then regulated by an ultra-low current buck-boost converter for the BLE module and sensors. A voltage regulator with a battery monitor tracks secondary battery levels. An optional RIOT-C01 board allows charging from a CR2032 coin battery.
Parts used in the RIOT-001 Environment Sensing Board:
- BME280 temperature/humidity/pressure sensor
- MAX44009 ambient light sensor
- Riot-001 Environment Sensing Board
- RP124 voltage regulator with battery monitor
- BLE module with MCU
- AD converter inside the BLE module
- Solar battery panel
- Li-ion secondary battery
- RIOT-C01 Coin Battery Board
- CR2032-type coin battery
Ricoh Electronic Devices Company RIOT-001 Environment Sensing Board is designed to transmit data obtained from a temperature/humidity/pressure sensor (BME280) and an ambient light sensor (MAX44009) via Bluetooth, to tablets or other smart devices. The board also includes a voltage regulator with a battery monitor (RP124) for the measurement of the secondary battery voltage.
The RIOT-001 Board is ideal for indoor lighting using a solar battery panel. The RIOT-001 Environment Sensing Board efficiently harvests the electric power a solar battery panel generates. This happens using the buck DC/DC converter for energy harvest then stored in a small Li-ion secondary battery. The stored power is supplied to a BLE module with an MCU and sensors by the RP604, an ultra-low supply current buck-boost DC/DC converter.
The RIOT-001 Board also includes the RP124, a voltage regulator with a battery monitor, to monitor the secondary battery voltage. Checking the state of the secondary battery voltage is possible by transmitting battery information to tablets or other smart devices through an AD converter inside the BLE module.
RIOT-C01 Coin Battery Board
The RIOT-C01 Coin Battery Board is an optional board for the RIOT-001 environment sensing board. This board features a battery holder for a CR2032-type coin battery. The RIOT-C01 board charges the secondary battery mounted on the RIOT-001 that provides the environment sensing operation with a coin battery.
