1) What is the typical use case for HP-YJ32?
Long-term remote monitoring of static/slow-changing signals in SHM and geotechnical projects (settlement, displacement, strain, pressure, temperature, cracks, etc.).
2) Can I mix different sensor types in one system?
Yes. Each channel can be configured independently for different input types (voltage/current/bridge/vibrating-wire/thermocouple, etc.).
3) How often can it record data?
From 1 sample/second down to 1 sample/day (0.0001–1 Hz), set by software.
4) How does it prevent data loss?
It supports dual backup: local TF card storage plus remote server upload, including resume after communication interruption.
5) What communication options are available on site?
USB, RJ45 Ethernet, and 433MHz wireless (up to 200 m) for local access; GPRS/4G for remote transmission.
6) Is it suitable for outdoor installation?
Designed for outdoor exposure (−20°C to 60°C) with rain/dust/lightning protection features.
7) How long can it run on battery?
It supports lithium battery power for multi-day operation; solar charging can be added for continuous online monitoring (exact runtime depends on configuration and site conditions).
