SenseCAP Indicator D1 is a 4-inch capacitive touch screen IoT development platform powered by dual MCUs (ESP32-S3 + RP2040), designed for local dashboards, sensor hubs, and smart-home integrations. With Wi-Fi, Bluetooth LE, and optional LoRa®, rich Grove/GPIO expansion, and fully open-source firmware, it enables rapid prototyping and production-ready IoT applications. Built-in air-quality sensors (CO₂, TVOC) support out-of-the-box monitoring, while the platform’s openness allows deep customisation and integration with ecosystems like Home Assistant, Matter, Node-RED, AWS, and more.

Key Features

Dual-MCU architecture: ESP32-S3 + RP2040 for UI and real-time control
3.95-inch capacitive RGB touch display (480 × 480)
Wi-Fi 2.4 GHz and Bluetooth 5.0 LE connectivity
Optional LoRa® (SX1262) for local LoRa hubs and long-range devices
Built-in CO₂ (SCD41) and TVOC (SGP40) sensors
External Grove temperature & humidity sensor support (AHT20)
Rich GPIO and Grove interfaces for easy peripheral expansion
USB-C power and data; Micro SD support up to 32 GB (not included)
Fully open-source firmware and SDKs across ESP32 and Raspberry Pi ecosystems

Use Cases

Air Quality Monitor

Use the built-in CO₂ and TVOC sensors to create a desktop or wall-mounted air-quality display.

Smart Home Dashboard

Build a local control panel for Home Assistant, Matter, or Node-RED with touch interaction.

IoT Sensor Hub

Aggregate local sensors via Grove/GPIO and forward data over Wi-Fi or LoRa®.

Developer Prototyping Platform

Rapidly prototype UI-driven IoT applications using open-source tools and libraries.

Data Display & Information Panels

Create weather stations, stock tickers, SOP reminders, or digital photo frames.
