Deskripsi

Overview

Sensor nirkabel bertenaga surya yang bekerja dengan sistem HOBOnet untuk memantau suhu udara dan kelembapan relatif. Sensor nirkabel HOBOnet mengkomunikasikan data secara langsung ke stasiun HOBO RX3000 atau HOBO MicroRX, atau meneruskan data melalui sensor nirkabel lainnya kembali ke stasiun pusat. Sensor-sensor ini telah dikonfigurasikan sebelumnya dan siap digunakan

Features
