Summary of RICOH ELECTRONIC DEVICES COMPANY LAUNCHES THE RIOT-001 ENVIRONMENT SENSING BOARD
Ricoh Electronic Devices Company RIOT-001 Environment Sensing Board summary: The RIOT-001 transmits temperature, humidity, pressure (BME280) and ambient light (MAX44009) data via Bluetooth to smart devices, while harvesting solar power with a buck DC/DC converter to charge a small Li-ion secondary battery. It powers a BLE module with MCU and sensors using the RP604 buck-boost converter and monitors battery voltage via the RP124 regulator with battery monitor. The optional RIOT-C01 coin battery board holds a CR2032 to charge the secondary battery. Specs include 2.0–5.5V input, ~16.4µA average current, and 0–50°C operation.
Parts used in the RIOT-001 Environment Sensing Board:
- BME280 temperature/humidity/pressure sensor
- MAX44009 ambient light sensor
- BLE module with MCU and AD converter
- RP604 ultra-low supply current buck-boost DC/DC converter
- Buck DC/DC converter for energy harvesting
- RP124 voltage regulator with battery monitor
- Small Li-ion secondary battery
- RIOT-C01 coin battery board (optional)
- CR2032-type coin battery (used with RIOT-C01)
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.
