The image below shows my sensor node enclosure. The enclosure is an air-tight box where all electronics ( MSP430FR5969, batteries, C110L tranceiver) will be fixed inside. A total of four PVC elbows with 12 inches pipes are mounted on two longer sides of the air-tight box for sensor probes that will be submerged in the water. Additionally, upward pipe on one of the shorter side is also mounted for the Air temperature and Carbon dioxide sensors. A 5W soloar panel is placed in an inclined position ...
This is a continuation of Post#4 , data received through UART in Beaglebone board is displayed in terminal. My problem the last time is that I can't send data to AirVantage using MQTT since my Beaglebone is behind university proxy. MQTT is using default port 1883 as reserved with IANA. To avoid this problem, I will be using REST API instead. In this post, data will be sent to AirVantage using Python with REST API.   About AirVantage:     Sierra Wireless AirVantage M2M Cloud p ...
In this week's post, I will be using a transceiver connected to a UART of BBB to collect data. Cool features of Beaglebone Black rev C Hardware setup Using UART of BBB   Cool features of Beaglebone Black:      This is the first time I use BBB and below are some of the cool features I love during the first few days of use. This board is amazing and I'm sure there will be more features to enjoy. Processor. 1GHz chip with 512 of DDR3 RAM OnBoard Flash Memory. Referre ...
Title: Low Cost Harmful Algal Bloom Monitoring In post#2, I have identified the sensors, microcontroller and transceiver to be used for the sensor node. For this week to complete the whole system, detailed on the 2nd subsystem(the receiving end) will be illustrated. A. Aggregator node: This node collects data from one or more sensor nodes through CC110L transceiver, but this node has more functions than just receiving data. Using CC3200 wifi Launchpad, the node will act as MQTT c ...
Title: Low Cost Harmful Algal Bloom Monitoring Recap: This is my second post. Last week, I gave a brief introduction on what is HAB (Harmful Algal Bloom) and its impact (economic, environmental and health). I also gave its cause including the role of climate change (temperature and Carbon dioxide) in frequent occurrence of HAB. On the technical side, I gave an overview on how the system would be setup and look like. Basically the system can be divided into two subsytems: the wireless sensor node ...
Hi everyone!   This is my first design challenge and got really excited when I first learned my proposal was accepted. Many thanks Dr. Defeo and sponsors (Texas Instruments, Wurth Electronics, Cisco, element14, Eclipse, Sierra Wireless) for the opportunity. Never had the chance to  use  Beaglebone, TI launchpads and other tools in this challenge before, so I'm excited to start playing with these cool and powerful boards once I receive the challenge kit. To readers, just ...
