In this age of increasingly advanced technology and the growing importance of Internet of Things (IoT)-based solutions, the smart home is no longer a luxury but is becoming a modern lifestyle standard. One of the most important components of any Smart Home ecosystem are temperature sensors, which play a key role in providing comfort, security and efficient energy management.
Sensylink Microelectronics Inc. is a high-tech company specialising in the design of advanced integrated circuits and mixed-signal sensors. Since 2015, it has been continuously developing a portfolio of proprietary solutions, already offering more than 300 products with full intellectual property rights.
The brand's components are used in industrial, automotive, medical applications and, above all, in modern Smart Home systems and consumer electronics, where reliability and precision are key.
The CHT8315 is one of the most popular sensors among designers of Smart Home and HVAC systems. It features exceptionally low power consumption - just 1 µA at one measurement per second - and a wide supply voltage range of 1.35 V to 5.5 V.
Temperature readout precision is ±0.3°C and humidity ±2.5%RH, which, combined with full support for I²C and SMBus interfaces and transmission protection functions (PEC, Alert Response), makes this sensor ideal for smart climate control systems, wearables and air purifiers. Compatibility with popular Sensirion and TI models makes migration into existing designs easy.
For applications requiring an analogue signal, the CHT8336 provides a modern alternative, combining simplicity of integration with high accuracy. It operates at 1.8-5.5 V and offers a typical current consumption of 220 µA at two measurement cycles per second.
Accuracy of ±0.5°C for temperature and ±4.0%RH for humidity in the key range makes it ideal for environmental control systems and modern domestic appliances. A built-in 16-bit ADC guarantees a high level of detail, while an optional shield increases resistance to the elements.
If your project requires exceptional measurement accuracy and minimal energy consumption at the same time, the CHT8325 will be the best choice. The sensor operates over the full temperature range from -40°C to +125°C, offering ±0.3°C and ±2.5%RH precision with an average current consumption of 5.5 µA.
In sleep mode, it requires just 0.36 µA. Support for I²C and SMBus protocols, full compatibility with models from Sensirion and Texas Instruments, and NIST compliance tracking make it ideal for advanced HVAC equipment, mobile environmental sensors and next-generation weather stations.
CT7112 is a digital temperature sensor designed for applications where the balance between energy efficiency and accuracy matters. It operates from -40°C to +125°C, offering ±0.5°C over a typical range and a resolution of 0.0625°C thanks to its 12-bit ADC.
Its low power consumption (3 µA) and support for I²C, SMBus and 2-wire interfaces make it a natural choice for handheld devices, room sensors, HVAC systems and consumer electronics.
For projects where scalability and minimising the number of communication lines is important, the CT1721 is the perfect choice.
A particular example of the practical application of the CT1721 sensor is in modern fridges and freezers, where precise temperature control is required in multiple zones simultaneously.
Thanks to its digital pulse output, in which the number of pulses is proportional to the temperature value, the sensor allows up to nine independent measuring points to be connected to a single microcontroller pin, significantly simplifying system wiring. The use of the CT1721 simplifies the connection architecture, improves production efficiency and significantly reduces overall system costs.
In addition, the digital form of communication provides much better resistance to electromagnetic interference, which is particularly important in environments with a lot of electronics. The built-in measurement precision - reaching ±0.5°C over a range of -10°C to 80°C - makes this model a digital sensor with very high data reliability, ideal for next-generation refrigeration and domestic appliances.
Compatible with the popular LM75 chip, the CT75 is an upgraded version with increased functionality and better performance. It operates from 1.75 V to 5.5 V, offering an accuracy of ±0.5°C over the typical range and a resolution of 0.0625°C.
A current consumption of 3 µA at one conversion per second and the ability to set up to 32 different addresses thanks to three addressing pins make this chip a flexible and energy-efficient solution for a wide range of applications - from wearables to home electronics.
The CT7433 is a four-channel temperature sensor designed for applications requiring simultaneous monitoring of multiple measurement points, such as servers, computers or telecommunications equipment.
It offers three remote and one local channel with an accuracy of ±1.5°C and a resolution of 0.0625°C. With support for thermal CPU/GPU/FPGA diodes, ARA functions and programmable temperature thresholds, the CT7433 provides full control over thermal conditions in reliability-critical environments.
