Exo Sense Py

Added to your shopping cart

Exo Sense Py is an extremely versatile indoor environment sensor. It combines the computing power and wireless capabilities of the Pycom development boards with several environmental sensors and input/output lines.

Exo Sense Py embeds temperature, humidity, air quality, pressure, light and ambient noise sensors. Two digital input/output lines and an open-collector output line are also standard. It can optionally have a factory-installed earthquake sensor module, PIR sensor and real time clock module with battery back-up.

An ESD-protected RS-485 bus is available for wired serial communication using the industry standard Modbus protocol or any other half-duplex serial protocol.

Exo Sense Py ships without any Pycom board, so you can use your preferred Pycom development board, as far as it is fully compatible with the Exo Sense Py pinout and fits the Exo Sense Py case.
