PRODUCT INFORMATIONPDEM Series Gas Sensor Evaluation ModuleFeatures:* Available with Figaro MOS/EC/Catalytic/NDIR sensor* Pre-calibrated by typical target gas* Realtime monitoring of gas concentration, temp. /hum.
* Digital (I2C/PMODTM) and analog output* Temp. and hum. compensation of gas sensor raw signal* Compatible with Renesas Quick-connect IoT system
Model PDEM5141

Description:

The PDEM series evaluation module is designed to facilitate the evaluation of the MOS, electrochemical, catalytic and NDIR types of Figaro gassensors. Every PDEM module is individually pre-calibrated in the Figaro factory and can provide digital (I2C) or analog output of gas concentration
data (or IAQ index data by air quality sensors). Thanks to an integrated Renesas temperature and humidity sensor HS4001, the module includes
a temperature and humidity compensation function for the raw gas sensor output signals, and is capable of simultaneous ambient temperatureand humidity monitoring.
※The mounted sensor is not replaceable at customer's end.
Quick-Connect IoT Platform:
Quick-Connect IoT is a modular prototype development platform offered by Renesas Electronics Corp.
The Quick-Connect compatible hardware and software products from Renesas Electronics facilitate the prototyping of IoT systems comprisingof microcontrollers, sensors, and wireless communication modules.
