MAX1668EVKIT is a multifunctional precision thermometer and sensor evaluation kit. The kit is designed for easy evaluation and application of the MAX1668 Precision Multifunctional Thermometer with Dual Local Temperature Sensors. It provides numerous features that make it attractive for use in a wide variety of sensors that need to monitor local temperatures.

Applications

The MAX1668EVKIT provides an accurate and versatile evaluation to customers who need to monitor and measure temperatures in a wide variety of environments. The kit is particularly useful for environmental sensing applications, as it accurately measures temperatures in a wide range of local temperatures, from -50°C to +125°C. In addition, the kit is particularly useful for applications requiring precision measurements, such as medical and aerospace applications. It can also be used for alternative energy solutions such as solar cells to measure temperatures in extreme conditions.

Working Principle

The MAX1668EVKIT combines two independent thermometer sets into one platform, allowing it to measure two local temperatures from -50°C to +125°C simultaneously. These two temperature sensors are interfaced to the I2C bus so that they can be read from the MAX1668EVKIT controller. Each of the two temperature sensors has onboard precision analog-to-digital converters (ADCs) within the MAX1668 chip which allow for high-precision measurements.

The MAX1668EVKIT comes with a voltage supervisor which provides power to the sensor. The supervisor monitors the supply voltage and will power the system off if the voltage drops below the specified level. This ensures that the accuracy of the kit is preserved even when the voltage supply fluctuates or fails. In addition, the supervisor monitors the power line and will power off the system if there is an interruption in the line.

The MAX1668EVKIT also has an onboard temperature measurement algorithm which allows it to measure the temperature of each of the two temperature sensors and interpolate the results for a precise temperature measurement. The kit can measure temperatures from -50°C to +125°C in increments of 0.5°C. The algorithm uses a variety of conditions including peak detection, gradient measurement, temperature filtering, and hysteresis to ensure that accurate temperature measurements are obtained.

Finally, the MAX1668EVKIT is capable of both local and remote temperature monitoring through its connection to a variety of communication protocols including I2C and 1-Wire. The interface can be used to monitor temperature measurements at various locations in a system or to create a system wide monitoring application.

Conclusion

The MAX1668EVKIT is a versatile, precise, and cost effective solution for monitoring temperatures in a wide variety of applications. Its two independent temperature sensors, integrated voltage supervisor, and onboard temperature measurement algorithm make it ideal for monitoring local temperature in applications such as solar cells, medical, and aerospace applications. The kit also includes an onboard communication interface which makes it suitable for remote temperature monitoring applications. For these reasons, the MAX1668EVKIT is an attractive solution for applications requiring accurate and reliable temperature monitoring.
