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.
