This promotional package includes both an S2-141-SS PAR-FAR sensor with a 30 cm cable and microCache Bluetooth micro-logger at a special introductory price. When paired, these two devices are a powerful tool for monitoring photosynthetically active radiation with research-grade accuracy for optimal plant growth. The S2-141-SS PAR-FAR sensor is a unique two-channel sensor for measuring both the PAR (PPFD) and Far-red outputs of electric grow lights.
The new AT-100 microCache (µCache) micro-logger is a rugged, standalone, battery-powered device that can collect over 400,000 data points and connects your sensor to your iOS or Android device via Bluetooth using our free ApogeeConnect app. The app allows you to make real-time measurements, set custom datalogging intervals, monitor and graph daily lights integrals, assure photoperiods, download datasets, and more.
