The Hope RF 68621 sensor, developed by Hope RF, is said to represent a new benchmark in environmental sensing technology. The sensor is available from authorised distributor Anglia Components.
This advanced digital barometric pressure and temperature sensor is engineered for applications that demand exceptional accuracy, low power consumption, and robust performance in challenging environments.
At the heart of the sensor lies a capacitive pressure sensing element, a proven technology that ensures high precision and stability across varying temperatures. This makes the sensor particularly suitable for dynamic outdoor conditions and industrial environments where reliability is paramount.
Hope RF says that the sensor combines engineering excellence with practical design. Its waterproof housing and compact dimensions (6.8 x 6.2 x 3.1mm) enable seamless integration into space-constrained devices without compromising durability. Whether deployed in mobile devices, sports equipment, or industrial monitoring systems, the sensor delivers consistent performance under harsh conditions.
A defining feature is the sensor’s integrated signal processor, which converts raw pressure and temperature readings into 24-bit digital outputs.
Each sensor undergoes individual factory calibration, and the resulting calibration coefficients are stored in dedicated registers.
These coefficients allow the host processor to compensate for non-linearities, ensuring highly accurate pressure and temperature measurements across the entire operating range.
The digital pressure sensor delivers high precision results, with an absolute pressure accuracy of ±1.0 mBar and relative accuracy of ±0.1 mBar the sensor has a pressure range from 300 to 1200 mBar, temperature accuracy is specified at ±0.5°C.
The sensors digital I2C interface allows for easy integration with the system host processor. The sensor offers a configurable sampling rate from 1 to 128Hz, enabling designers to optimise for either power efficiency or data responsiveness.
An internal FIFO buffer capable of storing up to 32 measurements reduces the need for frequent host polling, significantly lowering overall system power consumption – a critical advantage for battery-powered applications.
Industrial operating temperature ranges from -40 to +85°C and features low standby current of just 0.5uA (Typ.) allowing use in battery powered applications. Peak current consumption is 345μA (Typ.) during pressure measurement and 280μA (Typ.) during temperature measurement.
The Hope RF digital pressure sensor is suitable for applications including mobile weather stations, industrial equipment, smart gas meters, sports monitoring devices, IoT devices, data loggers, and any equipment which requires high accuracy pressure measurement.
