01Overview

Engineered for the field

This multi-channel data logger collects temperature and humidity from two to four probes and uploads the readings over dual-band Wi-Fi (2.4 GHz and 5 GHz) to the environmental cloud platform. A low-power LCD shows live values on site, a built-in buzzer raises high and low limit alarms, and up to 65,000 records are stored internally as a backup. The integrated lithium battery keeps the logger running for around 45 days at a 10-minute upload interval, and an external 5 V supply can be used for permanent installations. WPA/WPA2 security and DDNS support make it straightforward to connect to existing site networks.

02Key Features

What makes the THL-332 different

01

Up to four probes

One logger monitors two to four temperature and humidity points, cutting hardware per site.

02

Dual-band Wi-Fi

Connects over 2.4 GHz or 5 GHz Wi-Fi using the site's existing network, with WPA/WPA2 security.

03

On-site display and alarms

A low-power LCD shows live values and a built-in buzzer sounds on high or low limits.

04

Battery backup and storage

Built-in lithium battery and 65,000-record memory keep data safe through power or network outages.
