ZRD16 Pyroelectric infrared sensor module adopts high performance PIR sensor and Pyroelectric dedicated LDO chip. It has the features, as low static power consumption, wide operating voltage, and high sensitivity. This module can be triggered repeatedly. If it’s detected again during sensing output delay time, the delay period will be recalculated.


  • Air conditioners, smart fans, smart door locks
  • Security products,
  • Human body induction toys, Human body induction lamps, switches, and appliances


Automatic Induction (when people enter into its sensing area, it gives an high-level output; when people leave the sensing area, it closes high-level output by 1s automatic-delay, and gives an low-level output.)
Photo-resistor control:
This module has no photosensitive control function,
And it detects the whole day.
Repeatable trigger mode: after high-level output, on the delay period, if there is human activity in its sensing range, the output remain high-level, and will not convert from high-level to low-level until people leave and the delay period is over. (when the sensor module detects every human body activity, it extend a delay period automatically, and use the last activity time as the starting time of delay period.)
Induction blocking time(default setting as 2s second): after every sensing output(from high-level to low-level output), a blocking time can be set. At this period, the sensor does not receive any sensor signal. By this function, it can realize interval working, to be applied to interval detection production. At the same time, this feature can inhibit all kinds of interference generated by the switching of load.
High-level output: TTL output, easy to interface with kinds of circuits;

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to

Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
