It is designed for compact, cost-effective indoor monitoring nodes where stable CO₂ readings are needed without complex hardware integration.An onboard SHT40 sensor adds ambient temperature and humidity measurement, giving you three environmental values from one module. The temperature and humidity data are also used for automatic compensation of CO₂ readings, while the built-in Automatic Self-Calibration algorithm supports long-term stability.The module communicates over a standard Gravity I2C interface and operates from 3.3 V to 5 V, making it suitable for Arduino, ESP32 and Raspberry Pi projects. The plug-and-play Gravity connector helps avoid soldering, breadboards and level-shifting in typical setups.It is supplied with the Gravity STCC4 CO2 Sensor x1 and Gravity 4Pin Cable x1, and is well suited to indoor air quality monitors, HVAC automation, smart home systems, classrooms, IoT nodes and STEM experiments.Features:High measurement accuracy: Based on the TC principle for stable and reliable dataLow power consumption: Suitable for battery-powered or always-on systemsCompact size: Easy to integrate into space-constrained and modular designDigital output: I2C interface with strong anti-interference capabilityPlug and play: Standard Gravity interface, no soldering requiredSpecifications:Supply Voltage: 3.3–5.0 V DCOperating Temperature: 10°C ~ 40°COperating Humidity: 20% ~ 80% RH (non-condensing)Operating Current Peak: 4.2 mAOperating Current Continuous Measurement: 950 μAOperating Current Single-shot Mode: 100 μA (10s sampling interval)Operating Current Deep Sleep: 1 μACO₂ Measurement Range: 400–5000 ppmCO₂ Accuracy: ±(100 ppm + 10% of reading)Response Time: 20 sInterface: Gravity I2C ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDRksBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--e96cbda10019cd8e77bcc82716665607d696c348/SEN0678_Main_01.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDUEsBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ed8ab3666c733966804ca0aa72cc1fdaede4866f/SEN0678_Dim_02.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDWksBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ead141b6d0df8fad78478b114d965cab00328b4b/SEN0678_Back_03.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDZEsBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--2c9111548121915fdaaed28b387cbb0ac4c32d80/SEN0678_Detail_04.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDaEsBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ca99773798cb11f3ceb5421f1a1e2f4e2f6a1767/SEN0678_ShipList_05.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
