WTS200A dual-channel wireless sensor is a non-real-time, medium-precision passive resistor strain sensor measurement and transmission, mainly used in industrial field, the main features include 10bit precision of the resistive divider measurement circuit, maximum 20dBm (100mW) with FEC coding FSK wireless transceiver circuit and battery power management and so on
The WTS200A is a dual‑channel wireless sensor designed for temperature, humidity, and hazardous gas measurement. It supports point‑to‑point communication up to 1 km and is used in construction, fire safety, and security applications.
The manual details the hardware interfaces (DC power, SMA antenna, JP pins), performance parameters (10‑bit ADC, 1200‑115200 bps data rates), and typical application circuits, enabling users to configure and integrate the sensor into their systems. This manual is written in Chinese.
