1. Transmitter senses triple relative-humidity figures
   Shyam Tiwari
   Circuits Wireless Measurement TE Connectivity HS1101LF
   The circuit in Figure 1 is a triple, relative-humidity sensor and radio transmitter. Sensors 1 and 2 form two gated oscillators with natural frequencies of 10 and 5 kHz, respectively, at relative humidity of 50%. The gated oscillators use variable ...

   Circuits Measurement Supply TE Connectivity HS1101LF
   Using ac-line power sources and batteries for remote humidity sensors is undesirable because these sources can be troublesome if you mount them in inaccessible points, such as smokestacks, cold-storage chambers, or darkrooms, where maintenance is ...

3. Impulse-Controlled Sequential Switch Without Active Electronics
   Circuits TE Connectivity RT424F24
   Marek Irek Electronic Design This circuit uses two electromechanical relays to realize a sequential switch that’s permanently resistant to electrical disturbance, remembering its state despite power failure and consuming energy only when ...

4. Relay-Based ON/OFF Flip-Flop Remembers State During Power Failure
   Circuits TE Connectivity PB1114-ND PB2024-ND
   Tommy Tyler Electronic Design This circuit uses electromechanical relays to retain its state indefinitely, even when power is off. It consumes no power except when triggered from one state to the other. Many varieties of ON/OFF control circuits use ...
