Welcome back to our Open Manufacture<\/a> series, where we reveal the intricate process of crafting exceptional products. Today, we’re diving into the world of extreme temperature testing, a critical step in ensuring the reliability and resilience of SenseCAP T1000 trackers.<\/a> Understanding how our devices perform under extreme temperature conditions is crucial, as it ensures that they continue to function flawlessly in the harshest environments, from freezing cold to scorching heat.<\/p>\n\n\n\n

Our goal with the SenseCAP T1000 is to guarantee optimal performance in the most challenging conditions, ranging from as low as -20\u00b0C to as high as 60\u00b0C. To validate this feature, we embarked on an extensive temperature testing journey, pushing our trackers to their limits.<\/p>\n\n\n\n

The Testing Process<\/h2>\n\n\n\n

We placed over 150 trackers into a specialized temperature test chamber, ready to endure the extremes. The devices were divided into two batches: one batch remained off, while the other actively transmitted data, set to different modes, such as transmitting data every 5 minutes or 30 minutes.<\/p>\n\n\n

Our temperature test was divided into two parts:<\/p>\n\n\n\n

Part 1: From Arctic Chill to Desert Heat<\/strong><\/h4>\n\n\n\n

In the first part, both batches of devices endured a frigid -20\u00b0C environment for 48 hours. Then, the temperature was raised to a scorching 60\u00b0C for another 48 hours. Throughout this 96-hour ordeal, we diligently monitored the active devices to ensure they functioned normally.<\/p>\n\n\n\n

Each device in the test had a corresponding Excel sheet where the results were meticulously recorded. The test results for device 2CF7F1C05180000F is given below.<\/p>\n\n\n\n

Following this extreme temperature cycling, all devices were retrieved for testing. Devices that were initially off were powered up to check for any startup issues, and a comprehensive functionality test was conducted on all devices. Additionally, we conducted a physical examination to check for any deformations, comparing the thickness of each device before and after the test.<\/p>\n\n\n\n

Part 2: Temperature Variations Challenge<\/strong><\/p>\n\n\n\n

In the second part of our testing, the devices were once again subjected to extreme temperature variations. The temperature test chamber started at -20\u00b0C and gradually increased by 10\u00b0C per hour, eventually reaching a sizzling 60\u00b0C before descending once more.<\/p>\n\n\n\n

This phase included the same tests as part one, with a unique focus on verifying the accuracy of the internal temperature sensor readings. T1000 records the temperature multiple times at each interval, and the results showed a discrepancy within an acceptable range, a reassuring sign of the device’s precision. To visually demonstrate these results, we’ve included a photo below:<\/p>\n\n\n\n
