Product details

Made possible by exploring innovative molded plywood techniques, Iskos-Berlin’s Soft Edge Chair blends strong curves with extreme lightness to create a three-dimensionality not usually possible with 2-D plywood.

Description

Comprehensive 3-in-1 Telemetry: Delivers concurrent digital readouts for temperature, relative humidity, and barometric atmospheric pressure on a single PCB footprint.
Dual-Core Hardware Precision: Combines a specialized ASAIR AHT20 moisture element with a premium Bosch BMP280 absolute pressure sensor.
Seamless I2C Bus Protocol: Interfaces via a single multi-device I2C serial link, supporting clock frequencies from 100kHz to 400kHz.
Perfect BME280 Alternative: Offers an accessible, highly modular, and budget-friendly alternative to full integrated environmental ICs.

Important Notes:

Ensure both Pull-Up resistors are correctly handled on your shared I2C lines to prevent signal dropping during high-speed ODR transfers.
Do not block or touch the white microscopic sensor membrane layout on the AHT20 IC surface.
When deploying inside sealed, moisture-heavy agricultural housings, protect the board traces with conformal coating while keeping the sensor apertures clear.
Do not score or mechanically warp the edges of the module layout when securing mounting hardware screws.
