Oiyagai 2pcs AM312 Mini Pyroelectric PIR Sensor Module Manual Motion Infrared IR Detector SR301

Product Information

The multisensor connects to Home Assistant via Wi-Fi and is set up with ESPHome and powered by a Micro-USB cable. No soldering needed! After understanding these concepts: interrupts and timers, let’s continue with the project. Schematic

Repeatable triggering mode: If a cat moves in the sensing range during the delay period, and output is high, output will remain highFor fastening the motion sensor to the lid. If you don't have a pistol already, this is a great addition to the household for both kids and adults. In the loop(), when the motionvariable is True, we turn the LED on for 20 seconds and print a message that indicates that motion was detected and which pin caused the interrupt. if motion: float temperature = static_cast(static_cast((getControllerConfig().isMetric ? sensors.getTempCByIndex(i) : sensors.getTempFByIndex(i)) * 10.)) / 10.;

Intelligent Infrared Technology: Modelled after the renowned SR501, the AM312 boasts superior infrared sensing capabilities. Before proceeding with this tutorial you should have the ESP32 add-on installed in your Arduino IDE. Follow one of the following tutorials to install the ESP32 on the Arduino IDE, if you haven’t already. optional: Before using rules configure any GPIO that doesn't have anything connected to it as Relay1. 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. It is designed to run at 3 volts and the module provides this using a HT7530-1 low dropout smdregulator.PIR Human Motion Module 10*8mm 2S delay time SB00322A-1 - Nanyang Senba Optical And Electronic, China

This Hudson Reed Traditional Shower Kit stands out with its dual functionality, featuring a fixed and adjustable shower head, catering to your unique showering preferences.

I did some experiments wrt the resistor placement, but by now, all are just without one (but I can also state: one can see a difference)

If you don’t use Wagos, find a way to connect all sensors needing Vin and GND to the 3.3V and GND stripped wire, respectively. As I have some problems with my RS485 setup the following is somehow preliminary (seems the 12V to 5V conversion is root cause; this also affects the RCWL's): Compact Design: With a PCB dimension of just 10mm x 8mm and a total size of approximately 12mm x 25mm, the AM312 is perfect for space-constrained projects. Take a look at the sensor threshold for the sound sensor and generally all the delta values. If you need more or less precise measurements, you may want to alter these values. Altering the values will impact the amount of traffic on your Wi-Fi and disk requirements for your Home Assistant instance. Higher deltas and threshold equals less traffic and less disk use. Lower deltas and threshold equals more traffic and more disk use.

Don't overwrite all your existing ESPHome settings. If you do, you won't find your newly flashed ESP32, OTA won't work and you must start over. The multisensor.yaml is clear on what parts you should leave alone. 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! When you have ESPHome up and running on the development board, disconnect the board from the power source and connect wires to the 3.3V and GND pins. Strip the other end of the wires, then:
