Weather and Level Adapter
Introduction
The Sentient Things Weather and Level Adapter is a board that plugs into the IoT Node Header to provide interfaces to the following sensors:
Maxbotix range sensors (up to two)
The Weather and Level Adapter includes an on-board MPL3115A2 pressure and altitude sensor.
Description
The board includes logic to select one of two Maxbotix range sensors using the N_D5 pin on the IoT Node Header. Level translation is provided to operate the Maxbotix sensors at 5V. Onboard jumpers enable optional inversion of the Maxbotix signal for sensors that output RS232 compatible serial (idle low).
Level conversion circuitry interfaces with a 1-wire device (DS18B20) operating at 5V.
