It digitises the tiny thermocouple signal and provides temperature readings with 0.25℃ resolution over a very wide measurement range.Instead of using a separate data line for every probe, the module communicates over a Gravity Single Bus 1-Wire style interface. Multiple CT1780 units can be daisy-chained on a single data line, which is handy for multi-zone temperature monitoring in ovens, kilns, furnaces, BBQ smokers and lab setups.An onboard DIP switch helps identify individual sensors in a multi-point network, working alongside the unique 64-bit address used by the 1-Wire protocol. The package includes the CT1780 amplifier board, a K Type thermocouple and a Gravity 3-pin cable.Features:Cold-junction compensation: Improves accuracy when measuring with a K-Type thermocouple.1-Wire communication: Uses a simple single data line for temperature data.Daisy-chain support: Multiple sensors can be connected on one data line.Onboard DIP switch: Allows a user-defined address for easier physical sensor identification.Unique 64-bit address: Uses the addressing capability inherent to the 1-Wire protocol.Extreme temperature range: Supports K-Type thermocouple measurements from -270℃ to +1372℃.High resolution: Provides 14-bit / 0.25℃ temperature measurement resolution.Specifications:Input Voltage: 3.3~5.5V DCThermocouple Type: K TypeMeasurement Range: -270℃~+1372℃Operating temperature range of the amplifier board: -40℃~+125℃Temperature measurement resolution: 14 bit/0.25℃Temperature measurement error: ≤±2℃（-200℃~700℃）, ±4℃（700℃~1350℃）Communication Interface: Gravity Single BusAmplifier board size: 44*22mmWell suited to DIY reflow ovens, ceramic and pottery kilns, metal forging and smelting, custom BBQ or smoker loggers, and scientific temperature measurement. ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDTEsBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--8dadf8c67b6acccbd1b27951862d0966ca7c412d/SEN0656_Main_01-1.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDWEsBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--505502d475cbdd70b4fe9c134576e267d4b2c903/SEN0656_Dim_02.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDY0sBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--57af5eb12d102348ab5df565a1d72a2071d95d87/SEN0656_Detail_04.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDaksBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--7f86807899453a5dd32a0a6676f7f03e055097d3/SEN0656_ShipList_05.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDbksBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a00685519f3aa8cbf771294895b4660e610ab5cb/SEN0656_Main_01.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).
