Temperature Measuring Tool: OMEGA CL3515R thermocouple Measurement Location: Backside thermal pad of the XIAO ESP32S3 Testing Firmware: WebCamera Power Supply: Type-C 5V Operating Duration: 1 hour Key result: The device equipped with the heat sink maintained stable operation for over an hour, reac...
UsingLC resonance principles, the device excites inductors, detects oscillations, and calculates inductance with high accuracy. It is capable of measuring: ✔Toroidal inductors ✔Power inductors ✔Surface-mount (SMD) inductors ✔Air-core inductors To enhance measurement resolution, it featuresdual ...
To get epoch/Unix time, we create theGet_Epoch_Time()function which will return the current epoch time whenever a request will be made to the server. This section of code shows the function and how it returns the time. // Get_Epoch_Time() Function that gets current epoch time unsigned ...

The most common and widespread localization technique used for positioning with wireless access points is based on measuring the intensity of the received signal (received signal strength indication or RSSI) and the method of "fingerprinting". Typical parameters useful to geolocate the wireless access ...
Your tutorial about ESP32 ADChttp://microcontrollerslab.com/adc-esp32-measuring-voltage-example/is really interesting, as well as other ESP32 articles, thanks. For using ADC2 while WiFi activated, you said: “I will explain more about it in later parts of this series of tutorials.”. Have...
Interrupt Latency– is the time it takes the CPU to respond to a specific interrupt signal. It’s a measure for the response time of an interrupt and it’s desired to be as small as possible. Upon an interrupt signal reception, the CPU suspends the current main code executions, saves the...
data allows the ADS1256 to start measuring the new input channel sooner. Figure 19 demonstrates efficient input cycling. There is no need to ignore or discard data while cycling through the channels of the input multiplexer because the ADS1256 fully settles before DRDY goes low, ...
