Mini IR Pyroelectric Infrared PIR Motion Human Body Sensor Module

The pack failed to arrive.

Looks great.Havent tried them yet,but they look like the ones I have had before so Im shure they will work fine.

Looks like good stuff.

O modelo está correto, falta apenas testar.

Still need to test

Arrived in time, works as expected at a sensational price. In addition, a circuit diagram is given in the online description - a rare find in this shop! Hovever I'm not sure whether the diagram and the actual circuit really match - the diagram shows e.g. an LDR (light-dependent resistor) for daylight sensing that is not included on the PCB. Delay and sensitivity controls are on-board, there is a jumper to select retriggerable or non-retriggerable mode. Minimum 'on' time (after movement detection) is about 1 second, blocking time after switch-off about 4 seconds. Since the signal at the output pin is only around 3 V while active regardless of the supply voltage (perhaps useful for connecting an Arduino or similar), you need an NPN transistor as shown in the online description to get a higher and more powerful output signal, for connecting, e.g., a relay. Standby current consumption is only about 100 micro-Ampères with a 10 Volt supply.

Recibido antes del tiempo estimado, me falta probar

j'en ai commandé 3 trois pour un prix dérisoire, fonctionne parfaitement, je recommande

Received in <2 weeks. Works well.

Working very well has a great range
