Summary
1.BME280 Atmospheric Pressure Sensor
The BME280 is a low-power digital environmental sensor that integrates functions for measuring
atmospheric pressure, temperature, and humidity. It communicates with the main controller via an I²C
interface. With its compact size and stable performance, it is widely used in weather stations, indoor
navigation, IoT devices, and wearable technology, providing reliable environmental data monitoring
solutions. We offer customized interfaces to facilitate your connectivity needs.
2.Temp&Humi Sensor(GXHTV3)
The Heltec QuickLink Series element includes a wide variety of sensors and actuators. With a unified
packaging size and interface, the stamp hole allows it to be directly soldered onto your board like most
modules, also it can be optionally equipped with a PH2.0 x 4 interface to make it compatible with the
Grove Socket.
The GXHTC3 is a digital humidity and temperature sensor designed especially for battery-driven high-
volume consumer electronics applications. This sensor is strictly designed to overcome conventional
limits for size, power consumption, and performance to price ratio in order to fulfill current and future
requirements.
3.Buzzer
The buzzer compatible with WiFi LoRa 32 V4 can be directly installed on its expansion board by
selecting the B2B interface.

FAQ for Temp&Humi Sensor(GXHTV3)
1.How Can I use this Sensor with?
The sensor can be seamlessly integrated with the Sensor Hub Series by simply plugging it into the
board. This straightforward process allows for effortless connectivity and ease of use, allowing for
precise data collection and analysis.
2.May I inquire if the Sensor Hub Series supports the entire range of sensors?
The Sensor Hub Series is a set of devices that are designed to collect and process data from various
sensors. It is important to note that most of the Sensor Hub Series is supported, although some may
have specific requirements as indicated. This means that users can expect reliable and high-quality
performance from the majority of the devices in this series. However, it is recommended that users
consult the manufacturer’s documentation to ensure compatibility with their specific needs. By doing so,
users can maximize the functionality of the devices and ensure that they are able to meet their data
processing requirements.
3.May I inquire whether the item in question is impervious to water and dust?
The sensor in question is not equipped with water and dust-resistant properties. In order to attain such
capabilities, it would be necessary to employ the sensor within the protective enclosure of our Sensor
Hub Products.
