SenseCAP Indicator D1S

The SenseCAP Indicator D1S is a 4" touchscreen IoT development platform 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 D1S variant of the SenseCAP Indicator includes 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 (no LoRa functionality). 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). SenseCAP Indicator Model Comparison 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:
