We are happy to share a new sensor of ours, which is a pyroelectric based body detector, SPIR1.
We often receive suggestions to add pyro-infrared to radar sensors, and now we have decided to launch it as a standalone sensor first.
We used our findings on the 1M series to make this SPIR1 using the new ESP32-C3 series of modules and a very small selection of pyroelectric modules.
It's kind of fun to watch this little thing get triggered, even though PIR sensors have become ubiquitous, but still, this is a purely local PIR sensor that doesn't require the use of a gateway, and doesn't require the cloud.
Product Appearance
Principle of operation
PIR means Passive Infra-Red sensor which is passive infra-red sensor. It passes infra-red rays of 36.5 degree infra-red wavelength through a filter to detect active human targets.
Features
- Compact size
- TYPE-C USB powered
- ESPHOME integrated into HomeAssistant for convenience.
Product Specifications
- Sensor volume: 34mm diameter, 15mm height, 21mm height with IR lens.
- Blocking time: 2 seconds, 2 seconds off after triggering.
- Detection distance: 0-3.5m (maximum 5m)
- Sensor Model: SR602
- Firmware system: ESPHome
- Power supply: TYPE-C power supply, 5V 1A.
- Operating current: 80ma
- Connection: 2.4G WIFI
Application Scenarios
Used in conjunction with our radar sensors, it can reduce certain unnecessary interference and realize the activation of automation when IR is triggered and the shutdown of automation when the radar has no target.
Frequently Asked Questions
What does it look like in Home Assistant?
This is an attribute map of the current firmware, which currently has only one key attribute, whether the target is detected or not.
When someone passes by, the trigger scene looks like this:
How do I connect to HomeAssistant?
After configuring the device to the network via a hotspot, the device can be automatically discovered in HomeAssistant.
Do I need to install ESPHome addon?
No, the firmware is implemented using ESPHome, but it is simplified the whole connection process, just need to configure the network, join the same limitation network as HomeAssistant will discover the device.
Is it open source? Can I use it for DIY?
Yes, we will organize the yaml source code afterwards. Of course, you can also use Arduino code to make your own sensors, or use Tasmato, or the ESP-IDF native language.

This is a 5v powered sensor rather than the majority of PIR sensors which use batteries. I see many people in forums asking of their are mains-powered PIR sensors to reduce the number of battery operated devices. Of course that requires being close to a power source. Now if it only looked prettier.... You are forgetting the wife factor.
SCREEK:
It really isn't a satisfactory sensor in every way, and we're trying some new designs, but PIR is a very mature market anyway, so we don't have any more ideas than we want to try it out. Battery operation with a WIFI connection is unlikely, but still, it's a possibility for localization. I'm just glad it works. And in some ways I do feel lucky the radar sensor doesn't have to use such a hole or bump. Because I don't think these PIR sensor probes look really comfortable. We have a few more designs that we're trying out, and that kind of design would be a diaphragm to implement, kind of like Xiaomi's body sensors. But anyway, we finished it. In a way, we could do some experimenting with it ourselves.
Harry Fine@FB:
This Aeotec is the best looking PIR sensor that I've seen. Battery operated of course. If your new 5v one looked more like this.....
SCREEK:
This looks like a great design.Though it looks great overall, especially the not using batteries bit. But I still don't really like that eyeball thing in the center. Comparatively, I also like Xiaomi's design, which uses a sort of membrane design for the body sensor, and some of the doodles look like they do the same thing, and of course have batteries for those features. Our DIY products are not at all competitive like that, and that's something we've been wrestling with for a long time, but we just happened to have all these new resources on hand, and then we were testing these things as well, so we couldn't resist making it and releasing it. But no need to worry, our on-demand production mechanism keeps us from stressing about it, and we won't make some more unless someone actually needs them (we do have a little bit of shells stockpiled). But we can still test it ourselves, which is useful for us to understand the properties of these modules, to think about them. So it fits in with sharing this feature, but it's not a great business idea, which I totally get.
On that basis, as a first generation product it was born and I love the idea. Just like the first product of our radar line was actually the 1S (the 1W can be seen as a version of it going to the pro light sensor and display), it was a big oval structure, but these attempts helped us to familiarize ourselves with the radar module and have a great start. If and when the opportunity arises, we will continue to improve the structure of this PIR product as we are a very flexible organization. We can add ZIGBEE to it, add batteries, add membrane technology to cover the whole bump (we are already testing such materials). But we can't guarantee what will happen, it's just that there are already too many PIR sensors, and there's really no need to actually have an extra one, and with wires. Thanks for your valuable advice, you are always so wise!
