Sensor Data Services
Our expanding portfolio of sensor loggers provides clients with a wide range of design options.
Various sensor loggers can be combined to yield an optimal mix, while data acquisition in both end-of-day and live-streaming modes are always available with quick access via private, high-speed web services.
DHT Sensors
Our proprietary DHT sensor logging hardware provides continuous temperature and humidity data acquisition that is both accurate and reliable.
Two operationally independent modes of acquisition are available: End-of-Day processing for historical data management, and Live Streaming for easy monitoring of single or multiple DHT sensors. Virtual Ambient DHT data is provided using designated outdoor sensors which can reside at either the local site or any nearby remote site.
Temperature (Fahrenheit) and Relative Humidity readings, together with schematic solar elevation, are shown in this Live Stream snapshot.
PV Power Sensors
Photovoltaic power (PVP) systems with battery storage are the focus of our proprietary printed circuit loggers, used by clients for continuous acquisition of system voltage and system current measurements.
Our Standard PVP loggers provide acquisition of system voltage and net amps relative to the storage batteries, while our Dual PVP loggers provide acquisition of system voltage, storage battery charging amps, and system load amps (with which net amps can be computed).
Current sensors are designed for attachment to pre-existing shunts, or shunts installed for logging purposes.
In this snapshot, live data from a Dual PVP logger is charted. Included are summary statistics for current and previous daily periods. Daily periods start at sunrise and end at sunrise on the next day.
Customized Sensor Suites
Clients requiring acquisition of data from specialized sensors or sensor arrays are welcomed by our team. Using proprietary logger components or third-party products, we can rapidly develop customized, production-ready interfacing hardware.
Among our specialty systems, calibrated solar irradiance panel arrays provide reference data (shown below) that can be used to estimate performance characteristics for either planned or operational PV power systems.
This minutely chart depicts calculated solar elevation (cyan curve) along with power curves and summary statistics derived from data acquired using a 5-panel solar irradiance array deployed near Taos, New Mexico on a clear-sky day. The early morning “bump” from panel4 is caused by mesa albedo.
