Application of TS318_1B0814 thermopile sensor on stm32

This project is a piece of content used in my work. I have little talent and knowledge. If there are any omissions, please give me some advice. First, let’s introduce the TS318_1B0814 thermopile sensor. I uploaded the data used by this sensor on Baidu Cloud. To put it simply, this is an analog sensor. It […]

HP203B air pressure temperature sensor driver

Without further ado, let’s get straight to the code. The device tree code is as follows. It should be noted that the I2C device address described in the device is 7 bits, not 8 bits. Otherwise, the I2C subsystem will prompt that the device cannot be found when initializing. i2c3: i2c@50008c00 { compatible = “xxx-i2c3”; […]

ADC experiment (internal temperature sensor experiment) (photosensitive sensor experiment)

Introduction to Internal Temperature Sensor STM32 has an internal temperature sensor that can be used to measure the temperature of the CPU and its surroundings (the internal temperature sensor is more suitable for detecting temperature changes. When precise temperature measurement is required, an external sensor should be used). For STM32F103, the temperature sensor is internally […]

k-Wave丨Photoacoustic imaging simulation丨Definition of Gaussian sensor frequency response + comparison of simulation functions + setting of initial pressure gradient (5)

This article introduces– 1.How to define Gaussian sensor frequency response: How to express the frequency response of a detector (for example: piezoelectric ultrasonic transducer) when the response has a Gaussian shape, based on the example of a homogeneous propagation medium; 2.Comparison of simulated functions: Introducing a brief comparison between the simulated functions “kspaceFirstOrder2D” and “kspaceecondorder”.
