This promotional package includes both an SQ-500 Full-spectrum Quantum 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 SQ-500 sensor is a trusted industry standard for making accurate PPFD measurements. 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 ApogeeConnect app. The app allows you to make real-time measurements, set custom datalogging intervals, monitor and graph daily lights integrals, measure photoperiods, download datasets, and more.
