Description
The Honeywell DT8035 Dual Tec Motion Sensor is a hardwired motion detecting sensor that utilizes two types of motion detection methods. The device features built-in PIR and microwave sensors, and both sensor methods must be activated for the sensor to activate. This reduces false alarms.
The PIR sensor inside the DT8035 works by looking out for changes in infrared energy that occur with movement. If a person or large object comes into the field of view of the DT8035, the sensor will detect the change in passive infrared energy. The user can adjust the sensitivity of the PIR sensor in the DT8035 by increasing or decreasing its pulse count. A lower pulse count will reduce the area that a person or object needs to move through for the sensor to activate, thereby making it more sensitive.
As for the microwave sensor, it works by sending out continuous microwave signals. These sensors will return to the DT8035 in a set pattern based on the objects and structures in the room. The only way for this pattern is to change is if there is movement in the area. The strength of the signals can be adjusted to pass through objects and walls. In other words, the microwave sensor can actually detect motion outside the building if the signals are strong enough.
With the DT8035, both the microwave sensor and the PIR sensor must be triggered in order for the sensor to respond. This is very important for dual tec motion sensors with microwave functionality. Remember, microwave signals can detect motion that occurs outside the building if the signals are strong enough. But a PIR sensor will only detect motion that occurs within the same room. By using these technologies and capabilities together, it is very unlikely that false alarms will occur.
The DT8035 measures 3.86"H x 2.24"W x 1.71"D. It provides pet immunity for small animals weighing up to 100 pounds. The detector also features a look down sensor for detecting a person entering the room if placed directly above a door.

The Honeywell DT8035 is a hardwired dual tech motion sensor that uses both PIR and microwave sensing. It is built for residential use, and it features a large coverage area and pet-immunity for small animals. This sensor has few weaknesses, and it help to set the standard for what an end user can expect out of a good dual tech motion sensor. We think this is a great sensor, and we are particularly impressed with the excellent build quality from Honeywell. The Honeywell DT8035 gets a 5 Star rating from Alarm Grid.
There are many things we like about the Honeywell DT8035. As a dual tech motion sensor, it is less prone to false alarms than conventional PIR-only motion sensors. This can be extremely beneficial for users who may have had trouble with false alarms from other motion detectors. The sensor has a large coverage area of 40 feet by 56 feet, which is great for larger residential rooms. The sensor can work great in a spacious indoor area like a big living room, family room, or man cave. The sensor offers pet immunity for small animals weighing up to 100 pounds. This can be particularly important for households with larger dog breeds that may set off other motion sensors. There is a look down zone on the sensor, which helps it detect movement that occurs directly below (not used when pet immunity is desired). And we also appreciate the sensor's adjustable pulse count, which is good for adjusting the device sensitivity to meet the needs of the household.
The only real downside to this sensor is that it needs to be wired back to the panel. In addition to hard-mounting, this will also likely involve fishing wires through the walls. Most DIYers prefer to go the wireless route because installation is simply much easier. But if you are prepared to perform a proper setup and installation, then you will be rewarded with a reliable motion sensor that can serve your household for many years to come. This is an outstanding dual tech motion, and we give it 5 Stars.
Good: Less Prone to False Alarms, Large Coverage Area, 100 Pounds Pet Immunity, Look Down Zone, Adjustable Pulse Count
Bad: Must Be Wired & Mounted
Bottom Line: 5 Stars
