The SENTRY M1 RF is a Radio Frequency (RF) Superheterodyne receiver on a compact board designed to interface directly onto another PC board or microcontroller. It detects and decodes ASK (Amplitude Shift Keying) remote transmitter devices and pulses the output upon successful triggering of the receiver. This particular receiver is versatile because it has all of the sensitive RF electronics already built up, leaving only the output pin, grounds, and power pin exposed. This device can be used in a vast array of switching applications where an RF link is required and there are space or output power switching constraints.<\/p>\n","protected":false},"excerpt":{"rendered":"
The SENTRY M1 Radio Frequency (RF) module is a compact superheterodyne receiver module designed to detect Amplitude Shift Keying (ASK) remote control transmitters operating at 433.925MHz. The Sentry M1 is a versatile communication board that is designed to interface directly to the I\/O pin of any microcontroller or decoder IC (MC145028, HT12, ESP\u2026 etc). The module has an integrated data slicer, which provides clean demodulation (to TTL) levels of ASK signals typically generated by wireless remote controls. A level shifter may be required for use with microcontrollers that have 3.3V or lower I\/O requirements.<\/p>\n","protected":false},"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0},"product_brand":[18],"product_cat":[34,33],"product_tag":[],"class_list":{"0":"post-88","1":"product","2":"type-product","3":"status-publish","5":"product_brand-martin-electronics","6":"product_cat-403-mhz-recievers","7":"product_cat-receivers","8":"pa_gaurantee-warranty-sentry-products-are-manufactured-with-careful-consideration-to-detail-and-process-and-each-unit-is-manufactured-in-a-regulated-contaminant-free-environment-and-it-is-tested-under-strict","9":"pa_technical-specifications-technical-specifications-operating-frequency-433-925mhz-power-source-12v-24v-battery-type-approvals-icasa-ta-2004-741-etsi-300-220-1-bapt-zv-125-etsi-300-683-memory32-entri","11":"first","12":"instock","13":"product-type-simple"},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.martin-electronics.co.za\/index.php\/wp-json\/wp\/v2\/product\/88","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.martin-electronics.co.za\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.martin-electronics.co.za\/index.php\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.martin-electronics.co.za\/index.php\/wp-json\/wp\/v2\/comments?post=88"}],"wp:attachment":[{"href":"https:\/\/www.martin-electronics.co.za\/index.php\/wp-json\/wp\/v2\/media?parent=88"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.martin-electronics.co.za\/index.php\/wp-json\/wp\/v2\/product_brand?post=88"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.martin-electronics.co.za\/index.php\/wp-json\/wp\/v2\/product_cat?post=88"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.martin-electronics.co.za\/index.php\/wp-json\/wp\/v2\/product_tag?post=88"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
