SPI
temperature sensors
Ultra-fast and stable digital sensors, designed for industrial applications requiring reliable high-speed transmission via the SPI bus.
What is an SPI sensor ?
An SPI (Serial Peripheral Interface) sensor is a digital sensor that uses the SPI communication protocol to transmit data to a microcontroller or PLC. This protocol, widely used in industry and embedded electronics, relies on synchronous full-duplex communication: data flows simultaneously in both directions, offering high transfer speeds and great reliability.
SPI temperature sensors are used in environments where precision, responsiveness, and stability are essential. They generally consist of an integrated measurement probe and a digital processing circuit that converts data directly into a format usable by a PLC, microcontroller, or embedded system.

✽ What SPIs Offer
Discover the main four benefits
Ultra-fast communication
The SPI protocol allows transmission speeds far superior to I²C or 1-Wire interfaces. This ensures near-instantaneous temperature readings, even in critical environments where reaction time is essential.
Simplicity of hardware integration
SPI generally uses 4 lines (MOSI, MISO, SCK, CS), which makes it easy to integrate into printed circuits or embedded systems. Many microcontrollers are already natively compatible with this interface.
High data reliability
Thanks to its synchronous communication, SPI offers excellent signal stability, even in noisy industrial environments. The risk of read errors is reduced, making it a reliable choice for sensitive applications.
A wide range of available sensors
Compact, multi-parameter, or ultra-precise models: the SPI sensor offering is vast and covers needs ranging from simple thermal regulation to complex environmental monitoring.

Frequently asked questions
Here are some common questions about our SPIs.
An SPI sensor communicates with a microcontroller via the Serial Peripheral Interface protocol. This protocol uses dedicated communication lines (MISO, MOSI, SCK, CS) to transmit data quickly and reliably. The sensor sends a digital value directly, avoiding any analog conversion.
SPI offers higher transmission speed, better signal stability, and full-duplex communication. Unlike I²C, it has no strict limit on the number of devices, as long as each sensor has its dedicated chip select (CS) line. It is also less sensitive to electromagnetic interference than 1-Wire.
Integrating an SPI sensor requires an SPI-compatible microcontroller or PLC. You need to connect the MISO, MOSI, SCK, and CS pins. It's also important to correctly configure the clock frequency and SPI mode (0 to 3) according to the chosen sensor. Our datasheets detail the required connections and timing.
Yes. We develop custom SPI sensors according to your constraints: temperature range, usage environment, type of connector, acquisition frequency, or microcontroller compatibility. We support you from prototyping to mass production.
