Deskripsi
Overview
Sensor nirkabel yang bekerja dengan sistem HOBOnet untuk mengukur suhu tanah dan potensi air tanah, cara yang lebih akurat untuk mengukur berapa banyak air yang tersedia untuk tanaman. Sensor ini dirancang untuk tahan terhadap kondisi lingkungan yang keras, dan tidak memerlukan kalibrasi untuk jenis tanah atau salinitas yang berbeda. HOBOnet T21 dikalibrasi dalam sistem ruang yang memungkinkan T21 mengatur titik kalibrasi dari -10KPa hingga -80KPa. Dengan lapisan epoksi yang tahan lama, Anda dapat yakin bahwa sensor ini dapat digunakan di dalam tanah dalam jangka waktu lama, sekaligus memberikan data yang dapat Anda percayai.
