The SenseCAP Indicator D1Pro is a 4" touchscreen IoT LoRa development platform with sensors, designed for use in environmental monitoring applications.
It features a 4" capacitive display and is driven by a dual-MCU system combining the ESP32S3 and RP2040 chips. This D1Pro variant of the SenseCAP Indicator includes Wi-Fi, Bluetooth and LoRa communication, along with built-in sensors for TVOC and CO₂, and an external Grove temperature/humidity sensor, making it suitable for indoor air quality monitoring and similar use cases, with the benefit of LoRa communication.
The embedded SX1262 LoRa® module enables you to build the LoRa application and connect your local LoRa sensors to the Cloud via Wi-Fi. For example, you could build a LoRa hub device to connect your LoRa sensors to your smart home ecosystem to implement Matter over Wi-Fi. In this way, the LoRa devices could be connected to the Matter ecosystem via Wi-Fi, without the need to buy a new Matter-compatible device.
This device supports Wi-Fi and Bluetooth communication, and is fully open-source to enable flexible prototyping and customisation. It is part of the wider SenseCAP ecosystem and can be used for developing interactive interfaces and wireless sensor displays.
A USB-C cable is included for powering the device (5V 1A required).
There are four models of the SenseCAP Indicator, which might be a little confusing. Here's a comparison table to help you find the right version for your project:
Model | D1 | D1S | D1L | D1Pro |
---|---|---|---|---|
tVOC sensor | ❌ | ✅ | ❌ | ✅ |
CO₂ sensor | ❌ | ✅ | ❌ | ✅ |
Grove TH Sensor | ❌ | ✅ | ❌ | ✅ |
LoRa (SX1262) | ❌ | ❌ | ✅ | ✅ |
Wi-Fi | ✅ | ✅ | ✅ | ✅ |
Bluetooth | ✅ | ✅ | ✅ | ✅ |
We also stock the SenseCAP Indicator for Meshtastic & LoRa, which sits outside of this range.
