Sensor nirkabel pemenang penghargaan yang bekerja dengan sistem HOBOnet untuk mengukur kelembapan tanah dan suhu tanah pada berbagai kedalaman menggunakan satu probe, sehingga pemasangannya cepat dan mudah.
Tersedia dalam tiga panjang probe: 45 cm (18 in), 60 cm (24 in), dan 90 cm (35 in)
Pengukuran kelembapan tanah di sepanjang seluruh segmen probe
Pengukuran suhu tanah pada beberapa titik
Volume pengaruh terbesar per pengukuran (2 L volume pengaruh per segmen 15 cm)
Penyaringan lanjutan hingga 400.000 pulsa per pengukuran menghilangkan pembacaan yang menyimpang dan memberikan data kelembapan tanah yang presisi dan konsisten
Rumah polikarbonat dan papan sirkuit bersegel epoksi melindungi komponen penting selama pemasangan dan penggunaan di lapangan
Pemasangan mudah dengan gangguan tanah minimal, dan tidak perlu menggali saat menggunakan pilot rod dan slide hammer opsional
Teknologi mesh nirkabel Sub-GHz yang dapat memperbaiki dirinya sendiri (self-healing)
Jarak nirkabel 450 hingga 600 meter (1.500 hingga 2.000 kaki) dan hingga lima hop
Hingga 50 sensor nirkabel atau 336 kanal data per satu stasiun HOBO RX
Bergabung ke jaringan nirkabel HOBOnet hanya dengan menekan tombol
Memori internal untuk memastikan tidak ada kehilangan data
Ditenagai oleh baterai AA isi ulang dan panel surya bawaan
