IAQ-LOGR: Wireless Indoor Air Quality Monitor and Data Logger
The IAQ-LOGR is an Open-Source firmware application that implements a Wireless Indoor Air Quality Monitor and Data Logger. The IAQ-LOGR application base board hardware includes the following sensors and components.
IAQ-LOGR BASE PACKAGE:
- smSENSR-Si7006: Si7006 Temp/Humidity Sensor Breakout Board
- smSENSR-LTR-303: LTR-303-ALS Ambient Light Sensor Breakout Board
- smSENSR-Sunrise OR smSENSR-CM1106-SL: Low Power I2C/UART CO2 Sensors(firmware works with both)
- smMEM-MX25R6435F: MX25R6435 64Mb Serial Flash Breakout Board
- smCOM-FT230: FT230 USB-UART Breakout Board. Can also provide regulated voltage output.
- smWSP-ARD Rapid Prototyping Wireless Sensor platform(Arduino Compatible Shield)
NOTE!! This basic configuration requires a Nordic nRF52 DK to be used with it to provide the BLE functionality.
IAQ-LOGR LONG RANGE WIRELESS PACKAGE:
For a slight additional cost this package can provide complete stand-alone operation for the IAQ-LOGR and does not require a Nordic nRF52 DK to be used.
- IAQ-LOGR Base Board contents
- smRF-832LR: nRF52832 with +20dBm PA/LNA module plugin
- smLiPo-603450: 1100mAh Lithium Polymer Battery
- smPWR-MP2148: High Efficiency DC/DC Converter, 3.3V Output
Utilizing the sensors the firmware implements an Indoor Air Quality Monitor and Data Logger we call the IAQ-LOGR. The IAQ-LOGR firmware is open source under the Apache 2.0 license. The firmware implements an I2C interface to the individual sensors and implements a SPI interface for the Serial Flash. The application will data log the sensor data to the serial flash based on the user configurable Data Logging Interval and when connected to a BLE client such as the SENSR-LOGR Mobile app will synchronize the sensor data logs we call SENSR-LOGS to the BLE Client. The firmware provides a BLE interface that with the SENSR-LOGR mobile app allows for configuration of the Data Logging Interval along with Advertising Interval. Each sensor has individual configurations, alarms and sampling rates that can be configured via the SENSR-LOGR mobile app also. The SENSR-LOGR app also provides real time graphing and the ability to download the SENSR-LOGRS in a CSV file or push these logs to a Cloud Storage location.
The IAQ-LOGR application utilizes a unique rapid prototyping hardware base board called the smWSP-ARD. The smWSP-ARD is an Arduino R3 compatible shield that has standardized pinout I2C and SPI plugin blocks we call smBLOCKS. There are also additional smBLOCKS that support other functionality being USB-UART, Power Management, and RF/Wireless.
smWSP-ARD
The smWSP-ARD supports all Sensor Maestros smMEM, smSENSR, smMOTN, smCOM, smBAT, and smPWR breakout boards that plug directly into the smWSP-ARD using smBLOCKs to quickly plug in these pin compatible design components making it simple to swap in/out numerous different wireless, sensor, memory, and power configurations to completely customize your system and then just as easy to completely change it a day later. Gone are the days of having to work with a sensor evaluation board that has several sensors you would love to change but they are soldered directly to the PCB. Now you can pick and choose your RF, sensor, memory, power, and battery configuration. Secondarily all these components can then be un-plugged from the smWSP-ARD to be either used in a prototype of your own, in a bread-board application, or simply be replaced by a different smBLOCK compatible component.
- 4 I2C smBLOCKs: Can be used with any smSENSR and smMOTN products
- 1 SPI smBLOCK: Can be used with SPI compatible smMOTN, smSENSR, and all smMEM products
- 1 USB-UART smBLOCK: Can be used with any smCOM products(smCOM-FT230).
- 1 RF smBLOCK: Can be used with any smRF based products such as the smRF-LR832.
- 1 Power smBLOCK: Can be used with any smPWR products such as the smPWR-MP2148
- 1 LiPo Battery connector
- DIP Switches to enable individual Interrupt pins for each smBLOCK and SPI pins
- Compatible with all smMEM, smSENSR, smMOTN, smCOM, smPWR, and smRF plugins
- 1.25mm Battery connector
- CR2032 Coin Cell Holder(bottom of PCB)
Growing family of plugins Sensors(smSENSR), Power(smPWR), Battery(smBAT), Motion
Sensors(smMOTN), USB-UART(smCOM), and RF Radios(smRF) and Demonstration software to tie everything together.
