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 CO, 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).
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 | ||||
| CO sensor | ||||
| Grove TH Sensor | ||||
| LoRa (SX1262) | ||||
| Wi-Fi | ||||
| Bluetooth |
We also stock the SenseCAP Indicator for Meshtastic & LoRa, which sits outside of this range.
