When you have all the parts, and you are sure you can reach you ESP32 from Home Assistant, start off with printing the enclosure. It takes around 3-3.5 hours on the Ender-3 Pro on default settings. Don’t bother printing with printing supports. For the add:north E-PLA I use: extruder temp 215°C, build plate temperature 60°C, retraction distance 5,5 mm and retraction speed 35 mm/s. Sound detection is useful to measure ambient sound level. You won’t get an accurate dB-measurement, but an approximation. You can work with the values and thresholds to create custom notifications. The BOB-12758 (SparkFun Electret Microphone Breakout) mic with preamp is supposed to be more sensitive than the KY-037 and KY-038 alternatives. Its also smaller, and the KY-037 and KY-038 won't actually even fit the enclosure easily. To that end, I’ll keep a tally of replied experiences here. Please share your experiences by mentioning the number of successes vs failures of the 501 vs 312 sensors… failure let’s say is, 1 false trigger per week? Success over total, so the higher ratio wins.

My name is Angel and I bought your book “Learn Esp32 with arduino” and is really good! but in the “Multisensor Project” there is a fatal error in the code: The loop() function is constantly running over and over again. In every loop, the now variable is updated with the current time. now = millis(); The following snippet of code shows how you can use the millis() function to create a blink LED project. It turns an LED on for 1000 milliseconds, and then turns it off. /********* You can actually connect up to 8 sensors to each digital output for a total of up to 48 soil moisture sensors on a single Pro Mini + NRF24 and more if you want to resort to port expanders. (As stated before, port expanders are not really realistic due to them costing about the same as a whole Pro-Mini.) Not all Pro Minis expose all 8 analog pins, choose one that does if you want the most possible sensors.As said before, position it in a place where sudden temperature variations (within a couple of seconds) are not to be expected. Slow variations are fine as the circuit measures differential voltages in a window comparator or digital equivalent of that. There is no wrong polarity protection for the power pins. They are marked on the pcb with a very small “+” and “-” symbol. (see the first photo). The detectsMovement() function prints a message in the Serial Monitor, turns the LED on, sets the startTimer boolean variable to true and updates the lastTrigger variable with the current time. void IRAM_ATTR detectsMovement() { Connect the Rx and Tx wires to the pins on the board according to the figure. Remember that Tx from the sensor goes to Rx on the board, and vice versa!
Elevate your electronic projects with Kunkune’s AM312 Mini IR Infrared PIR Sensor. Designed with intelligent infrared technology, this compact sensor offers high sensitivity and reliability, making it an essential component for a range of auto-sensing applications. AM312 Mini Key Features: In this tutorial a list is shown with ESP32 interrupt types but the list is not correct! There are no HIGH or LOW interrupts, HIGH and LOW are equal to TRUE and FALSE, 1 and 0 resp. and should be used for logical purposes, not for interrupts.After 20 seconds, turn the LED off, and print a message to indicate that motion stopped. led.value(0)
