We designed Sensync Mini as the companion of Sensync Base for larger environmental monitoring area that meet customer's expectation: high spatial resolution. Sensync Mini can record various environmental data as it is highly flexible to be customized. It can be fitted with many environmental sensors to create larger networks as many as you can. We start offering you with basic air quality monitoring packages: temperature, humidity, O3 gas, CO gas, NO2 gas, and SO2 gas. Then, it can be expanded to include additional gas sensing measurement such as CO2 gas, NO gas, and H2S gas, not limited to automatic weather/meteorological system for wind characteristics and rain fall, environmental noise measurement, solar radiation intensity, and many other physical paramater.
As network expansion solution, our product concepts are:
- Continuous and Real-time Measurement
- Compact Design and Space-saving Dimension
- Modular Sensor Housing for Easy Maintenance
- High Sensitivity and High Selectivity
- Low Power Consumption
- On-board Back-up Data Storage
- Powered by Solar Module for Stand-alone Application
Basically, Sensync Mini directly exposed the target air or gas into measurement chambers, as shown in Fig.1. All sensors are placed in a single chamber connected with inlet and outlet ventilation. Our standard package consists of electrochemical gas sensors with very low detection limit and suitable for ambient monitoring. Our advanced micro-controller is pooling data and send data through GSM/GPRS networks as well as stored it inside on-board micro SD-card with size of 2 GB for back-up data storage. Additionally, Sensync Mini is powered by PV module with batteries so it can be used anywhere as long as GSM networks are available.
Through GSM/GPRS networks, every node of Sensync will transmit data via HTTP protocol to access internet as well as database server, as shown in Fig.2. The Sensync Dashboard as web-based application will help you to display and manage your data collection. It will automatically email you the Daily Report that shows data recap for whole day (e.g. number of data, average data, maximum and minimum value, and significant events). It also allows you to control your Sensync node for your specific need and preferences, such as measurement interval time, sampling number, node health, calibration, and threshold parameters. Furthermore, it can be included with Sensync Early Warning System that alert you immediately when transmitted data is beyond particular threshold parameters. The alerts are being sent to your email and phone by SMS.
We have been developed successfully Sensync Mini for BMKG, national agency, for portable urban air quality monitoring. Please see BMKG Study Case for further story.
