A sensor type (感知タイプ, Kanchi taipu; Literally meaning "Perception type") is ninja that is capable of detecting the presence of other people through their chakra. A skilled sensor can detect their targets from a great distance, as well as differentiate the characters by their chakra signature alone and sense potential disturbances in the chakra of other people. They are even able to tell when other sensors are using their abilities. There are, however, methods that can hinder a sensors ability to detect individuals. Muu has mastered the Hiding with Camouflage Technique to such extent that he is able avoid detection by traditional sensory techniques, but can be sensed through other means such as contact type sensory techniques (Gaara's sand, Kidomaru's web etc.). Karin is able to suppress her chakra though she herself cannot use her abilities while doing this. The Aburame can use their insects to create false chakra signals and confuse sensors. The Mirage Genjutsu used by the Second Mizukage and his Giant Clam also prevents them from being sensed through traditional methods while in effect. Even though there are several types of "sensory", the following rules apply to "natural" chakra sensors as most of the other sensor types are covered by the rules of their respective characters, abilities or clans.
- Canon characters that have shown clearly in the manga/anime to have sensing abilities, can use them like Karin, Ao, C etc. If they are bound by any other rules, those rules still apply (for example Ao is bound by the Byakugan rules and Inoichi by the Yamanaka rules).
- To make a custom sensor bio you need to have the permission from at least one RP mod.
- You can't have any other KG, HA, 8IG, SM or one of the custom Seven Swordsmen of the Mist in a custom sensor bio. You can however combine it with puppetry or smoke and your 2nd bio can still have KG/HA etc.
- You need to have had at least one earlier approved bio before you can ask permission for a custom sensor bio.
