Product Overview
The KL-DS33YA active wireless temperature sensor is a three-channel high-precision temperature sensor featuring wireless transmission and ultra-low power consumption. It consists of three temperature sensors, a signal modulation and amplification device, a logic control circuit, a wireless communication circuit, a lithium battery, and an antenna. The sensor uses ultra-low power wireless communication to transmit the collected three temperature data channels to the wireless temperature measurement host via a wireless network.
This temperature sensor is equipped with three temperature sensor probes, enabling it to simultaneously detect the temperature of three objects. It uses a strap-on mounting method, allowing direct contact with the object being measured for easy and secure installation.
This temperature sensor is primarily used and deployed in low-voltage switchgear environments, and can simultaneously collect the temperature of three objects being measured . Its cost advantage is particularly significant in scenarios involving large-scale deployment of electrical node temperature monitoring.
