DT20 Data logger - Fronttech（Beijing）Limited Data logger

WEATHER SENSOR

FRT DT20 Data logger

Model Number : FRT DT20

Overview

The DT20 data collector is a multi-purpose, low-power, and can be redeveloped (supporting LUA scripts) data collection device. By embedding LUA scripts, the collector can collect data from various sensors related to hydrology, meteorology, environment, and other fields, including RS485 RS232、 Voltage analog quantity, sine wave digital quantity, pulse digital quantity, etc. The collected data can be stored on an SD card, transmitted to the website backend or viewed directly through a serial port. The data collection time and data upload time of the collector can be set through scripts, and they are independent of each other.

Characteristic

Including software, independent configuration of coefficients through software
Equipped with enhanced DSP data functionality
9-30V wide power input range.
Durable and sturdy, suitable for use in various harsh environments
Secondary development can be carried out through configuring scripts
