Assisting the application of thermometers and hygrometers | Promoting the development of IoT environmental monitoring networks
A thermometer and hygrometer is a small electronic device used to monitor the temperature and humidity of the environment. Its design usually needs to take into account low power consumption, long life and high accuracy. Button batteries are an ideal power source for thermometers and hygrometers because of their small size, high energy density and stable discharge.
The core advantages of button batteries in thermometers and hygrometers
Volume and energy efficiency adaptability
Thermo-hygrometers often need to be embedded in small spaces (such as household sensors and industrial recorders). Button batteries (such as CR2032 and CR1220) are usually ≤20mm in diameter and only 3–6mm thick, which perfectly matches the needs of device miniaturization. Its energy density is significantly higher than that of cylindrical batteries. For example, CR2032 has a capacity of about 220mAh. Combined with the ultra-low power consumption design of the thermohygrometer, it can support continuous operation of the device without replacement.
Voltage stability and compatibility
The sensor of the thermometer and hygrometer (such as the digital humidity sensor) requires a stable voltage to ensure accuracy. The discharge curve of the button battery is gentle, such as the CR series lithium manganese battery with a nominal voltage of 3V and a small fluctuation range, which avoids data drift caused by voltage fluctuations.
Ultra-low power consumption technology enables long life operation
The long life of the thermometer and hygrometer depends on the coordinated optimization of hardware and firmware. The key technologies include: nano-level timer control wake-up cycle; highly integrated low-power chipset; typical power consumption model.
Typical application scenarios and representative products
1. Home and consumer electronics
A thermometer and hygrometer: uses CR2032 batteries, with low annual power consumption, and can be replaced by users.
2. Industrial wireless sensor network
TI solutions are networked through a star network below 1GHz, suitable for warehouse temperature and humidity monitoring, smart agriculture, etc.
NFC passive solutions are paired with CR1220 batteries. Users touch and read data with their mobile phones. It is suitable for low-frequency scenarios such as laboratory curing monitoring and plant maintenance, and has a very long life.
