Unveiling The Orno Or-cr-241: Exploring Specifications, Manuals, Pros And Cons, And Common Problems
ORNO OR-CR-241 Information
The ORNO OR-CR-241 is an ultra-flat passive infrared (PIR) motion sensor that can be used for automatic lighting control in indoor environments. It has a 360° detection angle and can be used with LED lighting. The sensor has two adjustable settings: the lighting time (TIME) and the sensitivity of the light intensity (LUX). The TIME setting can be adjusted from 10 seconds to 15 minutes, and the LUX setting can be adjusted from 3 lux to 2000 lux. The sensor also has a built-in daylight sensor that can be used to prevent the lights from turning on during the day.
The ORNO OR-CR-241 is a white, surface-mount sensor that measures 115mm in diameter and 24.3mm in depth. It has a maximum load of 2000W and a maximum load of 500W for LED light sources. The sensor is IP20 rated, which means it is protected against dust and splashing water. It is also certified to ENEC and CE standards.
The ORNO OR-CR-241 comes with a mounting bracket, screws, and an instruction manual. It is backed by a 24-month warranty.

As you can see, the ORNO OR-CR-241 is the most powerful motion sensor, with a maximum wattage of 2000 and a maximum detection range of 6 m. However, it is also the most expensive. The Aqara Motion Sensor is the most affordable option, but it has a lower wattage and detection range. The Sonoff PIR Motion Sensor is in the middle in terms of price and features.
Ultimately, the best motion sensor for you will depend on your individual needs and budget. If you need a powerful motion sensor with a long detection range, the ORNO OR-CR-241 is a good option. If you are looking for an affordable motion sensor, the Aqara Motion Sensor is a good choice. And if you are looking for a motion sensor with a good balance of features and price, the Sonoff PIR Motion Sensor is a good option.
Here are some additional notes about each of the motion sensors:
- The ORNO OR-CR-241 has a built-in light intensity sensor, so you can adjust the sensitivity of the sensor based on the ambient light level.
- The Aqara Motion Sensor has a built-in temperature sensor, so you can use it to trigger automations based on the temperature.
- The Sonoff PIR Motion Sensor can be connected to the Sonoff Cloud platform, so you can control it remotely and receive notifications when it detects motion.
ORNO OR-CR-241 Pros/Cons and My Thought
a summary of the pros and cons of the ORNO OR-CR-241 motion sensor, as well as some user reviews and my own thoughts:
Pros:
- Ultra-flat design makes it discreet and easy to install
- 360° detection angle covers a wide area
- Adjustable time and light sensitivity settings
- Can be used with LED lighting
- Max. load of 2000W
- IP20 protection rating
- 24-month warranty
Cons:
- Some users have reported false positives
- The sensor can be sensitive to heat
- The installation instructions are not very clear
User reviews:
- "I love this motion sensor! It's so thin and discreet, I can barely even tell it's there. I installed it in my hallway and it's been working great. It turns on the lights automatically when I walk by, and it's even adjustable so I can set the time and sensitivity to my liking." - Amazon reviewer
- "This motion sensor is a great way to save energy. I installed it in my kitchen and it only turns on the lights when I'm in the room. It's also really sensitive, so it doesn't miss any movement. I'm really happy with this purchase." - Home Depot reviewer
- "I've had this motion sensor for a few months now and I'm not really impressed. It's been giving me a lot of false positives, and it's not very sensitive to heat. I'm thinking about returning it." - eBay reviewer
My thoughts:
Overall, I think the ORNO OR-CR-241 is a good motion sensor. It's well-made and has a lot of features, including a 360° detection angle, adjustable time and light sensitivity settings, and the ability to be used with LED lighting. However, some users have reported false positives and the sensor can be sensitive to heat. If you're looking for a reliable motion sensor that won't give you any trouble, I would recommend the ORNO OR-CR-241. However, if you're on a budget or you're not sure if a motion sensor is right for you, I would recommend looking at some other options first.
Here are some other motion sensors that you might want to consider:
- Aqara Motion Sensor - This motion sensor is very affordable and has a lot of features, including a 360° detection angle, adjustable time and light sensitivity settings, and the ability to be used with HomeKit.
- Sonoff SNZB-02 Motion Sensor - This motion sensor is also very affordable and has a lot of features, including a 110° detection angle, adjustable time and light sensitivity settings, and the ability to be used with Alexa and Google Home.
- Philips Hue Motion Sensor - This motion sensor is more expensive than the other two options, but it has a few features that they don't, such as the ability to detect ambient light and the ability to be used with the Philips Hue ecosystem.
ORNO OR-CR-241 Problems and Solutions
some common issues and problems with the ORNO OR-CR-241 motion sensor, along with solutions from experts:
- The sensor is not detecting motion. This could be due to a number of factors, such as:
- The sensor is not properly installed. Make sure that the sensor is mounted on a flat surface and that the beam is not obstructed.
- The sensor is not sensitive enough. You can adjust the sensitivity of the sensor using the built-in controls.
- The sensor is not receiving enough light. If the sensor is in a dark area, it may not be able to detect motion.
- The sensor is turning on and off randomly. This could be due to:
- The sensor is detecting false positives. This can happen if the sensor is located in an area with a lot of moving objects, such as a pet or a tree branch.
- The sensor is malfunctioning. If you have tried all of the above solutions and the sensor is still turning on and off randomly, you may need to contact the manufacturer for a replacement.
- The sensor is not working with LED lights. This is because LED lights emit a different type of light than traditional incandescent lights. To fix this, you can use a LED bypass capacitor.
Here are some step-by-step instructions on how to install the ORNO OR-CR-241 motion sensor:
- Choose a mounting location for the sensor. The sensor should be mounted on a flat surface at least 2 meters above the ground.
- Secure the sensor to the mounting surface using the screws provided.
- Connect the sensor to the power supply. The sensor can be connected to a standard 230V outlet.
- Adjust the sensitivity of the sensor using the built-in controls.
- Test the sensor to make sure it is working properly.
Here are some step-by-step instructions on how to adjust the sensitivity of the ORNO OR-CR-241 motion sensor:
- Locate the sensitivity adjustment knob on the back of the sensor.
- Turn the knob clockwise to increase the sensitivity of the sensor. Turn the knob counterclockwise to decrease the sensitivity of the sensor.
- Test the sensor to make sure it is working properly.
I hope this helps!
