Waterproof Sensor Beacon with PA

Beacon with Blue low energy(BLE) technology.

Waterproof Sensor Beacon with PA 

Product Specification

Product Name: Temperature Humidity Sensor

Model Name: DSR-0820

1. Introduction

1.1 Description

 

DSR-0820 is Low Energy temperature and humidity data logger, It can collect temperature and humidity of the surrounding environment. Such data can be recorded as history data. Its characteristics are small-sized, low-weighted, easily portable and highly accurate for wide use in cold chain logistics, archives, labs, museums, etc.

At present, there are three different types of temperature and humidity sensors, DSR-0820-1 is a high performance product based on Bluetooth protocol,DSR-0820-2 is based on Zigbee protocol ,and DSR-0820-3 is a standard performance product based on Bluetooth protocol. DSR-0820-1 with the Bluetooth v5.0 technology and Nordic NRF52832 chip. Built-in wireless transceiver PA chip, the maximum transmission power up to 20dBm, to achieve ultra-long distance stable transmission of data, can store up to 12000 pieces of the temperature and humidity data.

 

DSR-0820-2 with the Zigbee 3.0 technology and Silconlab EFR32 series chip. the maximum transmission power up to 17.5dBm, to achieve ultra-long distance stable transmission of data. It can store up to 12000 pieces of the temperature and humidity data. 

 

DSR-0820-3 with the Bluetooth v5.0 technology and Nordic NRF52810 chip. the maximum transmission power up to 4dBm, Suitable for use at close range.
