UbiBot WS4-P4G1RS1C is a professional-grade environmental and location monitoring device designed for
applications that demand precise sensing, reliable connectivity, and real-time visibility. It integrates
high-accuracy temperature, humidity, light, and CO2 sensors while incorporating advanced GNSS tracking to
continuously monitor asset location and movement trajectories.
Equipped with GNSS positioning technology, the WS4-P4G1RS1C delivers accurate, real-time location data for
vehicles and mobile assets. Combined with 4G cellular connectivity, the device independently uploads both
environmental and positioning data to the cloud, enabling end-to-end visibility across transportation,
logistics, and remote deployments.
Featuring an RS485 interface, the device supports external sensor expansion for customized monitoring needs.
Its Flight Mode ensures compliance in wireless-restricted environments by completely disabling all wireless
communication while continuing local data logging, preserving data integrity without interruption.
An intelligent data acquisition system dynamically adjusts sampling and upload frequency, triggering alerts
when thresholds are exceeded. With up to 300,000 local records, the WS4-P4G1RS1C continues recording during
network outages and automatically syncs data once reconnected.
Protected by an IP65-rated enclosure and powered via Type-C with an internal lithium battery, the device
supports flexible installation and long-term unattended operation. Fully integrated with the UbiBot IoT Cloud
Platform, it provides centralized management, real-time visualization, and historical data analysis for
agriculture, cold storage, laboratories, and industrial monitoring.

The WS4 series device has an IP65 protection rating, which effectively prevents dust ingress and resists
low-pressure water jets. However, when exposed long-term to harsh outdoor environments (such as continuous
rainfall, high humidity, or intense sunlight), there is still a potential risk of moisture or rainwater
gradually infiltrating, which could affect the device's long-term stability and service life.
It is recommended that for outdoor use, the device be installed in a weatherproof outdoor distribution box
or other sheltered environment to enhance its reliability and durability in complex climatic conditions.
