Compare / every device in the collection

Compare the whole system, not just the count.

A complete monitor includes a display and matching sensing components. A standalone probe needs a host. An air monitor is not a water monitor.

4 complete monitors

Pool LoRa, Aquarium RS485, Wireless water and HY485. Check each system’s actual parameter set.

3 probe-only products

Standalone RS485, Aquarium monitoring and Pool LoRa replacement probes. A compatible host or display is required; no display or gateway is included.

1 environmental monitor

TH-WIFI measures air temperature and relative humidity. No water measurements.

8 devices / full names and system paths

Standalone RS485 salinity is displayed in ppt and %. These are two unit outputs, not two independent chemical sensors. None of the listed devices measures dissolved oxygen, ammonia, nitrite or nitrate.

Sensor link and app link differ

LoRa, wired RS485 and long-range wireless describe sensor-side paths. Complete systems use 2.4 GHz WiFi/Tuya for app connectivity. Probe-only products require a host.

Unknown is not a specification

Exact range, numerical accuracy, IP rating, battery life and chlorine measurement method are not established where supporting documentation is unavailable.

Readings need context

EC and TDS do not identify individual ions or pollutants. ORP is not chlorine concentration. These devices are not drinking-water safety tests.
