Ameba Arduino: [RTL8722CSM] [RTL8722DM] Upload PM2.5 Data to LASS System
Intro to LASS
The LASS stands for “Location Aware Sensor System”. It is an open project and was started only for the interest of public welfare. Find detailed introduction here.
Practically, LASS is based on MQTT protocol to collect all kinds of uploaded data, and for those who need these data can subscribe top as well. Find more LASS information at their official hackpad.
- Ameba x 1
- PlanTower PMS3003 (or PMS5003) x 1
In this example, we use applications mentioned at our website, including:
- MQTT: a MQTT-Broker to connect to LASS. The Client is “FT1_0XXXX”, the XXXX are the four last digits of Ameba’s Wi-Fi MAC, and the outTopic is “LASS/Test/Pm25Ameba/clientID“, where clientID is the actual Ameba’s MQTT client ID.
- NTP: uploaded data must have time notation
- PM2.5: uploaded data includes PM2.5 information
