Product Overview

The AST101/AST102 is a portable temperature and humidity sensor featuring an IP66 water resistance rating. The device is equipped with internal BLE 4.2 for wireless transmission, avoiding complex connections of communication cables, pipelines, and power cables. In this way, users can quickly install the device according to actual conditions. This reduces installation time and increases working efficiency. This device is equipped with a built-in battery to supply power, which can work for more than three years. It can be used for industrial monitoring, civil monitoring, machinery manufacturing monitoring, and environmental measurements, such as the laboratory, cleanroom, collection room, home, greenhouse, weather station, national defense science and technology research, posts and telecommunications, tobacco, chemical engineering, environmental protection, archives preservation and cultural relics protection, computer room, warehouse, medicine warehouse, medical health, hotel, food warehouse, grain, etc.
The highlights of the device are as follows:

• IP66 water resistance rating
• Temperature acquisition accuracy < ±0.5°C. Humidity acquisition accuracy: 0.05% RH.
• Built-in battery with 3–5 years of battery life
• At most 4 temperature and humidity sensors simultaneously supported by the T399L-GFB5

When the device is working, the blue LED indicator is off by default.
5.1 Setting the Bluetooth Temperature and Humidity Sensor
1. Connect the T399L to the computer through the USB cable, start Meitrack Manager, and then set the Bluetooth temperature and humidity sensor.

Alarm when signal lost for(secs): If the Bluetooth temperature and humidity sensor fail to be detected within the specified period, an alert is generated.
Trigger output when: Output 1 or output 2 is controlled when Bluetooth signals are lost, the temperature is too high or low, or the humidity is too high or low.
Control output: Output 1 or output 2 is controlled.
Report Data: Upload Bluetooth data or not.
MAC Address: indicates the MAC code of the Bluetooth temperature and humidity sensor.
Note: If the MAC code of the Bluetooth temperature and humidity sensor fails to be found, set it by the Meitrack Manager app.
2. Start the Meitrack Manager app, detect the T399L, and set the Bluetooth temperature and humidity sensor.

1. Start the Meitrack Manager app. Trackers will be detected automatically. After a tracker is detected, select one and click Confirm. Then the device configuration page is displayed.
   If a tracker fails to be detected, connect the white cable (input 2) of the device to the power cable (12–36 V) and the analog device to the ACC ignition cable. Then the device is switched to the broadcasting mode for one minute.

2. Set Bluetooth temperature and humidity sensor parameters.
   Select Temperature & Humidity Sensor. The MAC code of nearby Bluetooth temperature and humidity sensors will be detected automatically. Then select one sensor and set sensor parameters as required, as shown in the following figures.

Installation Instructions

6.1 Warnings
The device can be stuck on the surface of the following materials: aluminum, galvanized steel, enamel steel, stainless steel, ceramics, glass/epoxy resins, acrylic acid, PBT, ABS, PC, and hard PVC.
