Waterproof Sensor Beacon with PA
Product Name: Temperature Humidity Sensor
Model Name: DSR-0820
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.

Humidity detection accuracy
1) Being close to a metal object will interfere with the signal, causing the signal to be weaken.
2) Note the distance between DSR-0820 and the receiver to guarantee the accuracy of receiving.
3) Keep away from the corrosive objects.
5. Reference usage
1) Temperature & humidity sensor paired to the Bluetooth gateway.
2) Bluetooth Gateway get the data from the sensor and send the information to Cloud via Wi-Fi or LTE once per second.
